Some Interesting & Unusual Facts about the Human Body

We often say that we know everything about our body. But how much we do actually know about your own body? Here are some facts that may surprise you.

Skin

The largest organ in the body is the skin. In an adult man it covers about 1.9m2 (20sq ft).

The skin constantly flakes away – in a lifetime each person sheds around 18kg (40 lb) of skin

Nerve

There are 45 miles of nerves in the skin of a human being.

When we touch something, we send a message to our brain at 124 mph

Heart

In a year, a person`s heart beats 40,000,000 times. 

Circulatory system

The total length of your circulatory system stretches an amazing 60,000 miles. That is more than twice the distance around the Earth.

We give birth to 100 billion red blood cells every day and about two million red blood cells every second. 

Eye

Most people blink about 25 times a minute. The average human blinks his eyes 6,205,000 times each year.

Everyone is colorblind at birth.

Ear and nose

A sneeze zooms out of your mouth at over 100 m.p.h.

Your ears and nose continue to grow throughout your entire life.

Our hearing is so sensitive it can distinguish between hundreds of thousands of different sounds.

Our nose is our personal air-conditioning system: it warms cold air, cools hot air and filters impurities.

Stomach

The stomach’s digestive acids are strong enough to dissolve zinc. Fortunately for us, the cells in the stomach lining renew so quickly that the acids don’t have time to dissolve it.

The stomach has 35 million digestive glands.

When you eat meat and drink milk in the same meal, your body does not absorb any of the milk's calcium.

It is best to have 2 hours between the milk and meat intake.

Saliva

The average human produces a quart of saliva a day or 10,000 gallons in a lifetime.

Tongue

Like finger print, every person has a unique tongue print.

Teeth

The tooth is the only part of the human body that can't repair itself

Lung

The lungs contain over 300,000 million capillaries (tiny blood vessels). If they were laid end to end, they would stretch 2400km (1500 miles).

Liver

If a person has two-thirds of their liver removed from trauma or surgery, it will grow back to its original size in four weeks time.

The liver is often called the body's chemical factory. Scientists have counted over 500 liver functions. 

Body immunity

We have a whole pharmacy within us. We can create any drug inside us

Our bodies are recreating themselves constantly - we make a skeleton every 3 months, new skin every month.

Bone

More than half the bones in the human body are in the hands and feet.

A newborn baby has 350 bones, but a fully-grown adult has only 206

Brain

Our brain is more complex than the most powerful computer and has over 100 billion nerve cells.

Hair

It is normal to lose 100 hairs per day from the scalp.

Human hairs grow at an average of ½ to 1 in. a month or six to twelve in. a year.

Some more

A person can live without food for about 40 days, but only about 7 days without water, 6-8 minutes without air, and literally an instant without Life Force.

Human body has a tails too. The tail is about 1 to 2 in. long. It is the end tail of the spinal cord called coccyx.

Our Body produces carbon in such a rate, which is enough to manufacture 900 pencils.

Our bodies contain enough water to fill a ten-gallon tank.

10 Healthiest Foods & Their Nutritive Value

Food is any substance, composed of carbohydrates, water, fats and/or proteins, that is either eaten or drunk by any animal, including humans, for nutrition or pleasure. Food may be sourced from plants, animals or other categories such as fungus. A food with nutrient dense is called healthy food.

 Here is some listing of healthy foods, which has more nutrients per calorie than most other foods. They have also been proven to contain vitamins, minerals and other nutrients that prevent disease: from cancer to heart disease to arthritis, and many more. 


1.Fish 
Fish are good natural sources of calcium, phosphorus, iron and copper, and provide protein of unexcelled quality. Sea fish are also rich in iodine. Eating fatty fish at least three times a week is one of the healthiest things to do.


·   Salmon

A great source of omega-3 fatty acids, which have been linked to a reduced risk of depression, heart disease, cancer, inflammation and much more, plus it improves your nerves, eyes and brainpower. Salmon is also low in saturated fat and cholesterol and is a good source of protein. If possible, choose wild salmon, which is less likely to contain unwanted chemicals such as mercury.   


 2. Poultry

The poultry meat is not only tasteful, easy to prepare and appropriate for different food combinations, but also a natural source of: vitamins, minerals, proteins and healthy fats.
Skinless chicken and turkey are valuable sources of complete protein and B vitamins. Chicken soup really is good for colds and flu. Its high cysteine content helps break down mucus. White meat is easier to digest than fattier dark meat.


· Turkey  
Turkey is one of the leanest protein foods and is low in calories and high in selenium, making it an excellent healthy food choice. The selenium which strengthens the immune system, has been shown to inhibit cancer development, and aid in the metabolism of our thyroid hormone  


3.Vegetables

Vegetables with high nutritional values can give you the fiber, vitamins A and C, calcium, iron, magnesium and phytonutrient antioxidants that help prevent heart disease, cancer and other degenerative diseases. 


·  Vegetable juice 

This beverage is an easy way to include vegetables in your diet since it contains most of the same vitamins, minerals and other nutrients.  


·  Tomatoes

Tomatoes contain high levels of lycopene. Lycopene is a powerful antioxidant and as such helps to protect the cells in our bodies from damage. Tomato juice, and vegetable juices which include tomatoes, are good sources of lycopene, an antioxidant that may reduce the risk of heart attack and certain types of cancer. Be sure to select the low-sodium varieties.  


·  Grape Tomatoes

They're sweeter and firmer than other tomatoes, and their bite-size shape makes them perfect for snacking, dipping, or salads. They're packed with vitamin C and vitamin A, and you also get some fiber, some phytochemicals, and great flavor. 


·  Spinach

It's high in vitamin A and also is a good source of calcium, folate, iron, magnesium, riboflavin and vitamins B-6 and C. Spinach's secret weapon, lutein, makes it one of the best foods in the world to prevent cataracts, as well as age related macular degeneration, the leading cause of preventable blindness in the elderly. The plant compounds in spinach may boost your immune system and help prevent certain types of cancer. 


· Beans

Lentils, peas and other beans are good sources of fiber and B vitamins. Combined with whole grains, especially rice, they become an excellent source of complete protein. Beans have also been found to help lower cholesterol, regulate blood sugar and reduce cancer rates. Eating a serving of legumes (beans, peas, and lentils) four times a week can lower your risk of heart disease by 22 percent and also reduce your risk of breast cancer. 


·  Red beans

Small red, pinto and dark red kidney varieties -- are an excellent low-fat source of antioxidants, protein, dietary fiber and copper. They're also a good source of iron, magnesium, phosphorus, potassium and thiamin. 


· Broccoli

Broccoli (and other cruciferous vegetables like cauliflower and cabbage) Besides providing calcium, potassium, folate and fiber, broccoli contains phytonutrients -- compounds that may help prevent diabetes, heart disease and  helps fight cancers, especially breast, colon and lung. It boosts the immune system. Broccoli also contains antioxidants beta-carotene and is also an excellent source of vitamin C. 


4.Garlic and Onions

Garlic is a powerful natural antibiotic that can boost immunity, protect against bacteria including E. coli, parasites and viruses and help prevent heart disease, stroke and cancer. Onions are antibiotic, anti-inflammatory and antiviral and fight off bronchitis, asthma, hay fever and infection. Numerous studies have shown that regular consumption of garlic can lower our blood pressure. It also prevents the blood from being overly sticky and decreases LDL cholesterol (the "bad" one) while increasing the good HDL cholesterol. 


5. Yogurt

Plain, unsweetened, low-fat yogurt and other cultured dairy are excellent sources of complete protein, calcium and lactobacillus. They help protect against osteoporosis, cavities, high blood pressure, high cholesterol and intestinal disorders. It contains healthy bacteria that helps boost your immune system, fight infection and improve your gastrointestinal health act as a natural antibiotic and anticancer agent. 


6. Nuts 
Raw nuts are rich in protein, vitamins B and E, minerals and essential fatty acids. They’ve been found to have both anti-cancer and anti-heart disease properties. 


· Walnuts

Walnuts are an excellent source of omega-3 fatty acids, a special type of fat that is essential for our bodies, but that the body cannot produce. Omega-3 essential fatty acids protect us against heart disease. The antioxidant melatonin, found in walnuts, helps to regulate sleep 


·  Almonds

These nuts are packed with nutrients -- fiber, riboflavin, magnesium, iron, calcium and vitamin E, a natural antioxidant. They're also good for your heart. Most of the fat in almonds is monounsaturated fat, which can help lower cholesterol levels when substituted for other fats. Most almonds are considered low sodium, with less than 140 milligrams of sodium an ounce. Almonds are also known for their ability to help lower LDL cholesterol levels.




7. Sweet potatoes

The deep orange-yellow color of sweet potatoes tells you that they're high in beta-carotene. Sweet potatoes are also high in vitamin C and a good source of fiber, vitamin B-6 and potassium. And, they're fat-free and relatively low in calories.   


8. Whole Grains 
Brown rice, oatmeal, sprouted breads, and other whole grains are great sources of fiber, vitamins B and E, protein, minerals and essential fatty acids. High fiber foods help prevent colon cancer, high cholesterol and constipation. 


· Wheat germ 
The germ at the center of the wheat seed is a concentrated source of nutrients. Two tablespoons provide a good source of thiamin, folate, magnesium, phosphorus, iron and zinc. Sprinkle over cereals, yogurt and salads. Or use it in muffins, cookies and pancakes. 


· Oats

Oats also help reduce cholesterol. Research shows that one bowl of oatmeal per day can reduce cholesterol by up to 23%. Oats are also considered an excellent grain for diabetics as they have less impact on blood sugar levels than some other grains.
 
9.Fruit

Two to four daily servings of fresh or frozen fruit are recommended. Blueberries, raspberries, oranges, red grapes, plums, apricots and papaya are some of the best on the fruit list. They’re rich in fiber, vitamins, minerals, carotenoids and flavonoids 


·  Apples

Apples are a good source of pectin, a fiber that can lower cholesterol and glucose levels. They're also a good source of vitamin C -- an antioxidant that protects your body's cells. Vitamin C also keeps your blood vessels healthy and aids in the absorption of iron and folate.  


· Papaya

Papaya is an amazingly rich source of the proteolytic enzymes. These are the chemicals that enable the digestion of protein. As a cleanser take a quarter pint (150ml) of papaya juice alternated each hour for twelve hours by the same amount of cucumber or green bean juice. Papaya loses some of the enzymes as it ripens, so if you have the choice select them green. Papaya contains arginine which is known to be essential for male fertility and also carpain, an enzyme thought to be good for the heart. 
The skin of the papaya is a first class external treatment for skin wounds and places that do not heal quickly. The pulp from the juicer can be used for this and as a poultice. 


·  Berries

Berries are extremely rich in antioxidants which help protect the cells in our bodies from damage and therefore from diseases like cancer. Among other things they are also an excellent source of Vitamin C and soluble fiber. 


· Blueberries 
They are a rich, low-calorie source of fiber, antioxidants and phytonutrients. Regular intake of blueberries may improve short-term memory and reduce the cellular damage associated with aging.  


·Avocados

 

Avocado is considered the world's healthiest fruit, because of its nutrient contents such as vitamin K, dietary fiber, potassium, folic acid, vitamin B6, vitamin C, copper, and reasonable calories in it. Avocado is a good source of potassium, a mineral that helps regulate blood pressure. Adequate intake of potassium can help guard against circulatory diseases, like high blood pressure, heart disease, or stroke.  Adding it to your salad can increase the absorption of key nutrients like beta-carotene by three to five times compared with salads without this superfood. 


· Citrus Fruits

The citrus bioflavanoids in oranges, lemons, limes and grapefruit have anti-cancer and antioxidant properties. Many of these citrus bioflavanoids have also been shown to have anti-inflammatory and blood clot inhibiting abilities. Great-tasting and rich in vitamin C, folic acid, and fiber. Just one lemon has more than 100 percent of your daily intake of vitamin C, which may help increase "good" HDL cholesterol levels and strengthen bones. Citrus flavonoids found in lemons may help inhibit the growth of cancer cells and act as an anti-inflammatory. Add a slice of lemon to your green tea. One study found that citrus increases your body's ability to absorb the antioxidants in the tea by about 80 percent 


10.  Water

Water is a very essential nutrient in your diet. It’s needed for digestion, assimilation, metabolism, elimination, weight control and more. And unlike coffee, colas and alcohol, eight glasses of pure water a day have no calories or negative side effects.

How to Gain Weight Eating Healthy Foods - Health News

It may feel pretty lonely out there when everyone you know is trying to shed pounds and you are trying to put some on. However, your goals are exactly the same as those trying to lose some weight: To eat a healthy diet, and reach a normal body weight. It’s just as much of a challenge for the overweight person to lose pounds, as it is for you to gain them.

The good news is that it’s possible for all of you to sit at the same table, with the same menu, enjoy each other’s company, and reach your goals. You will be choosing a few things that they may be avoiding, but generally, eating healthy to gain weight involves eating the same variety of foods as your friends.

Whether you are underweight because of a recent illness, an eating disorder, or simply because your sense of taste declined as you grew older, the way to increase your weight is to increase the calories in your diet. To do this in a healthy way, you will not want to just add more junk foods to your diet. Junk foods don’t offer much nutritionally, and are loaded with unhealthy saturated fats and sugar.

Eating fish, nuts, and even seeds, routinely throughout the week will provide you with needed healthy fat and calories. Because red meat has a high saturated fat content, meals of this type would best be limited to one or two times a week.

Black beans, kidney beans, pinto beans, dried peas, and soy beans are all good sources of protein and calories. A delightful snack is easy to make by placing beans and cheese on a tortilla; roll it up, and microwave until it’s hot, enjoy.

Powdered milk added to soups, sauces, and smoothies, is a relatively effortless way to get bonus calories and protein.

Olive oil is a healthy diet choice because this monounsaturated fat will add calories to your diet, and help keep your cardiovascular system in good shape. For healthy salad dressings and mayonnaise, choose those made with canola or safflower oil.

The carbohydrates found in vegetables, fruits, and whole grains, infuse energy and nutrients into your daily diet. The USDA recommends that our daily diet include lots of grains and cereals; and that at least three servings a day are from whole gain breads, cereals, or and pastas. Whole grain carbohydrates provide calories, fiber, nutrients, and some protein in a healthy diet.

In the naturally calorie sparse vegetable group, starchy vegetables like potatoes and corn provide more calories, per serving, than the dark green vegetables; however, since dark green vegetables are important to any balanced diet, their caloric values can be easily supplemented by adding a little olive oil for flavoring, or toppings like slivered almonds, or grated cheese.

Fruits supply plentiful vitamins as well as phytochemicals which may possibly help prevent heart disease, cancer, and diabetes. Avocados are relatively high in calories, rich in monounsaturated fat, vitamin B and fiber. Bananas are also relatively high in calories, and can add an interesting taste to your morning cereal, or to a lunchtime peanut butter on whole wheat sandwich. Dried fruits can be used as healthy, high calorie snacks.

Replace sugary sodas with fruit juices to add calories, nutrients, and hydration to your diet.

Remember to take your multivitamins daily. Your healthcare provider can tell you if one of the many weight gaining supplements on the market today, is an appropriate way for you to add additional calories, protein, and carbohydrates to your daily diet.

Everyone eats desserts on occasion; a little chocolate is certainly good for the spirits. Your best choice in this category might well be something made with dark chocolate because it has anti-oxidants not found in other sweets.

One study found that people tend to eat more when eating with close friends, and also tend to eat more when eating with people who eat more. Socializing may be part of the answer; enjoy eating with your friends, especially those that really enjoy a meal; you’ll be having fun and eating your way to a healthy, normal weight.

Man-Made Earthquake - Top 5 Ways

"In the past, people never thought that human activity could have such a big impact, but it can," said Christian Klose, a geohazards researcher at Columbia’s Lamont-Doherty Earth Observatory.

It turns out, actually, that the human production of earthquakes is hardly supervillain-worthy. It’s downright commonplace: Klose estimates that 25 percent of Britain’s recorded seismic events were caused by people.

Most of these human-caused quakes are tiny, registering less than four on geologist’s seismic scales. These window-rattlers don’t occur along natural faults, and wouldn’t have happened without human activity — like mining tons of coal or potash. They occur when a mine’s roof collapses, for example, as in the Crandall Canyon collapse in Utah that killed a half-dozen miners last year.

But some human actions can trigger much larger quakes along natural fault lines. That’s because humans, with the aid of our massive machines, can sling enough mass around to shift the pattern of stresses in the Earth’s crust. Faults that might not have caused an earthquake for a million years can suddenly be pushed to failure, as Klose argues occurred during Australia’s only fatal earthquake in 1989.

Here are the top five ways to create an earthquake.

1. Build a Dam: Water is heavier than air, so when the valley behind a dam is filled, the crust underneath the water experiences a massive change in stress load. For example, the Hoover Dam area experienced hundreds of quakes as Lake Mead filled. University of Alaska seismologist Larry Gedney explained, "Since [the dam] reached its peak of 475 feet in 1939, the level of seismicity has fluctuated in direct response to water level.

2, Inject Liquid Into the Ground: In 1961, the Army decided that the best way to dispose of toxic waste from napalm production (among other things) was to drill a 12,000-foot-deep well in the Rocky Mountains and inject the bad stuff down it into the crust of the Earth. From 1962 to 1966, the Army deposited 165 million gallons of toxic waste into this hole in the Earth. Unfortunately, the injections probably triggered earthquakes in the region, and the Army shut the operation down. As seismologist Dave Wolny explained, "If you are doing deep well injection, you are altering the stress on the underlying rocks and at some point, the stress will be relieved by generating an earthquake."

3. Mine a Lot of Coal: Coal provides more than half the electricity in the United States and an even greater percentage in China. That means there are a lot of coal mines working overtime to pull the fossilized fuel out of the Earth. In total, miners pulled 6,195 million metric tons of coal out of the Earth in 2006 alone. And coal mines often have to pump water out along with the coal, sometimes extracting dozens of times as much water as coal. Add it up and you have a huge change in the mass of a region, and huge mass changes refigure the earthquake stresses of an area, sometimes increasing the chance of an earthquake and other times lowering it. Klose’s work suggests that more than 50 percent of the human-triggered earthquakes recorded came from mining operations.

4. Drill a Gusher Dry: Three of the largest human-caused quakes occurred near a natural-gas field in Uzbekistan, the Gazli. The combination of liquid extraction and injection changed the tectonic action in the field. The biggest of the trio registered as a 7.3. According to a major analysis (.pdf) by Russian scientists, "Few will deny that there is a relationship between hydrocarbon recovery and seismic activity, but exactly how strong a relationship exists has yet to be determined." They caution that in regions where tectonic activity is already high, extracting oil and natural gas could trigger strong quakes.

5. Create the World’s Biggest Building: Back in 2005, a geologist claimed that the world’s then-tallest building, the Taipei 101, which weighs in at more than 700,000 metric tons, was triggering earthquakes in a long-dormant fault in Taiwan. Klose doubts that the building actually did so, but said that it wasn’t outside the realm of possibility for a building to create an earthquake. The weight of the building, however, would have to be much greater than the Taipei 101’s, and even much larger than the Burj Dubai, currently still under construction but already the world’s tallest building.

No milk in tea please - Milk in tea may remove some of the heart health effects of black tea

Adding milk to tea totally wipes out the protective effect it has on the heart and blood vessels according to research published by the European Heart Journal.

According to the studies undertaken by scientists in Germany, black tea significantly improves the ability of the arteries to relax and expand. However, upon adding milk to black tea, the milk proteins counter this ability.

Experiments were carried out using laboratory rats and humans, measuring the endothelial function of the brachial artery before and after tea consumption.

Dr Verena Stangl, Professor of Cardiology (Molecular Atherosclerosis) at the hospital, explained “There is a broad body of evidence from experimental and clinical studies indicating that tea exerts antioxidative, anti-inflammatory and vasodilating effects, thereby protecting against cardiovascular diseases. As worldwide tea consumption is second only to that of water, its beneficial effects represent an important public health issue.”

The Five Biggest Lies in Obam's Health Care Reform - NEWSWEEK

To the credit of opponents of health-care reform, the lies and exaggerations they're spreading are not made up out of whole cloth—which makes the misinformation that much more credible. Instead, because opponents demand that everyone within earshot (or e-mail range) look, say, "at page 425 of the House bill!," the lies take on a patina of credibility. Take the claim in one chain e-mail that the government will have electronic access to everyone's bank account, implying that the Feds will rob you blind. The 1,017-page bill passed by the House Ways and Means Committee does call for electronic fund transfers—but from insurers to doctors and other providers. There is zero provision to include patients in any such system. Five other myths that won't die:

1. You'll have no choice in what health benefits you receive.
The myth that a "health choices commissioner" will decide what benefits you get seems to have originated in a July 19 post at blog.flecksoflife.com, whose homepage features an image of Obama looking like Heath Ledger's Joker. In fact, the House bill sets up a health-care exchange—essentially a list of private insurers and one government plan—where people who do not have health insurance through their employer or some other source (including small businesses) can shop for a plan, much as seniors shop for a drug plan under Medicare part D.

2. No chemo for older Medicare patients.
The threat that Medicare will give cancer patients over 70 only end-of-life counseling and not chemotherapy—as a nurse at a hospital told a roomful of chemo patients, including the uncle of a NEWSWEEK reporter—has zero basis in fact. It's just a vicious form of the rationing scare. The House bill does not use the word "ration." Nor does it call for cost-effectiveness research, much less implementation—the idea that "it isn't cost-effective to give a 90-year-old a hip replacement."

3. Illegal immigrants will get free health insurance.
The House bill doesn't give anyone free health care (though under a 1986 law illegals who can't pay do get free emergency care now, courtesy of all us premium paying customers or of hospitals that have to eat the cost). Will they be eligible for subsidies to buy health insurance? The House bill says that "individuals who are not lawfully present in the United States" will not be allowed to receive subsidies.

4. Death panels will decide who lives.
On July 16 Betsy McCaughey, a former lieutenant governor of New York and darling of the right, said on Fred Thompson's radio show that "on page 425," "Congress would make it mandatory…that every five years, people in Medicare have a required counseling session that will tell them how to end their life sooner, how to decline nutrition." Sarah Palin coined "death panels" in an Aug. 7 Facebook post.

5 .The government will set doctors' wages.
This, too, seems to have originated on the Flecksoflife blog on July 19. But while page 127 of the House bill says that physicians who choose to accept patients in the public insurance plan would receive 5 percent more than Medicare pays for a given service, doctors can refuse to accept such patients, and, even if they participate in a public plan, they are not salaried employees of it any more than your doctor today is an employee of, say, Aetna. "Nobody is saying we want the doctors working for the government; that's completely false," says Amitabh Chandra, professor of public policy at Harvard's Kennedy School of Government.

To be sure, there are also honest and principled objections to health-care reform. Some oppose a requirement that everyone have health insurance as an erosion of individual liberty. That's a debatable position, but an honest one. And many are simply scared out of their wits about what health-care reform will mean for them. But when fear and loathing hijack the brain, anything becomes believable—even that health-care reform is unconstitutional. To disprove that, check the commerce clause: Article I, Section 8.
