By a foot

The feet contain 26 bones, 33 joints, and more than 100 tendons.

The feet have 250,000 sweat glands.  They can produce more than a pint of sweat a day.

The average adult takes 4,000-6,000 steps a day.

Twenty to thirty percent of people have “Morton’s Toe”, where their second toe is longer than their “big” toe.

Fingernails and toenails grow at three millimeters (about a tenth of an inch) a month.

The length of your foot is the same as your forearm between the wrist and elbow.


That’s heavy

In the United States, the average man weighs 194.7 pounds; the average woman weighs 164.7 pounds.

The average height of an American man is 5 feet 10 inches, and for a woman the average height is 5 feet 5 inches.

The heaviest woman ever weighed 1200 pounds.

The heaviest man ever weighed 1400 pounds.

The average BMI is 27.3 for males (overweight) and 28.5 for females (overweight).

One third of U.S. citizens are obese (BMI over 30). One third of children and teens are  overweight or obese.

In the United States, 89 percent of women are unhappy with their weight. Of men, 45 percent are unhappy with their weight.

If a patient loses 5 pounds, it takes 20 pounds of stress off of each knee.

What are you made of?


Humans drink 16,000 gallons of water in their lifetime.

If a person drinks 2 liters of water a day, it increases their metabolism by 400 calories a day.

The human body is 70 percent water.

There is enough iron in your body to make a railroad spike.

Ten percent of a person’s body weight is from bacteria.

The biggest muscle in the human body is the gluteus maximus (the butt).  The smallest is the stapedius muscle in the ear.

On average, a person can live one month without food but only 7 days without water.

The bloody truth

More than 4.5 million patients need blood transfusions each year in the U.S. and Canada.

Someone needs blood every two seconds.

Only 37 percent of the U.S. population is eligible to donate blood.

One pint of blood can save up to three lives.

There are four main red blood cell types: A, B, AB and O. Each blood type can be positive or negative for the Rh factor. AB + is the universal recipient (can receive any blood type); O – is the universal donor of red blood cells.

The amount of blood you could donate if you begin at age 17 and donate every 56 days until you reach 79 years old: 46.5 gallons.

The amount of blood in the body of an average adult: 10 pints.

You  burn 650 calories per donation of one pint of blood!



Can you reduce your risk of dementia by 60%?

There are 5.5 million patients in the United States who have Alzheimer’s Disease.  The United States spends $259 Billion on health care for those patients currently, and drug companies are spending a fortune trying to find a treatment.

Current treatments have not shown significant response, though some medications offer some help for those afflicted.
Are there ways you can PREVENT Alzheimer’s disease?  There is a genetic component to the disease, but some measures have been shown effective at preventing Alzheimer’s dementia:
1.  Studies have shown that people who pursue intellectual activities such as reading, playing board games, puzzles, learning a second language, or playing musical instruments have reduced risk of Alzheimer’s Disease.
2.  Increased social interaction reduces Alzheimer’s risk.
4.  Moderate red wine use is associated with lower risk of Alzheimer’s.
3.  Increased physical activity has been shown to decrease the rate of Alzheimer’s dementia.
One study in particular is fascinating!  A study by researcher Peter Elwood at the Cochrane Institute of Primary Care studied 2,235 men age 45-59, and followed them for 30 years.
They found that those patients who did a few things reduced their risk of dementia by 60%!  This included eating a diet high in fruits and vegetables, maintaining a body mass index from 18-25, not smoking, and walking 2 miles a day.
If there was a drug on the market that we knew would reduce our risk of Alzheimer’s by 60%, we would all pay a lot of money to take it!

Liposuction Fun Facts

Liposuction, as you know,  is a type of cosmetic surgery that removes fat from the human body.

In the United States, liposuction is one of the most commonly performed cosmetic surgeries, and approximately 200,000 of these surgeries are performed a year.  The average cost of liposuction is $6000 per surgery.

The average amount of fat removed at a liposuction surgery is 5 Liters (about 1.3 gallons).

Unfortunately, recent studies have shown that liposuction benefit is short term, and after a few months the fat usually returns and re-distributes.

In one study, mortality from liposuction was 1 in 5000, although this number has been improving in recent years.  Some serious complications can include infection, bowel perforation, blood clots, blood loss,  and nerve damage.

In 2007, the captain of a boat converted  the boat’s engine to use fat removed from liposuction surgeries to power his boat, and sailed for 60 days!

Have a heart

The human heart beats about 100,000 times a day, sending 2,000 gallons of blood surging through your body.  In a lifetime, the heart will beat 2.5 billion times.

Laughing increases blood flow through the heart by 20 percent.

The average pulse for a man is 70 beats per minute, and 78 beats per minute for a woman.

The heart sends blood through 60,000 miles of blood vessels that feed our organs and tissues. But it only takes 20 seconds to circulate the blood through the entire human body!


That’s sexy!

In a woman’s lifetime, she will release 450 eggs from her ovaries.

The largest cell in a woman is the ovum released by the ovary.

A Y sperm (male) can swim faster than an X sperm (female) but not for as long.

Five hundred million sperm mature every day in a normal adult male.

The average lifespan of a sperm is 36 hours.

The average person has sex with 5 partners in their lifetime.

The average person has sex 2580 times in their life.

In the world, human sexual intercourse occurs 120 million times a day!

We all know that heavy alcohol consumptions is bad for you.

But what about moderate alcohol consumption?

In a very large review of over 100 studies about alcohol consumption and heart disease, researchers found that moderate drinkers have a 25-40 percent reduction of heart attacks, strokes, peripheral vascular disease, and death!(

Why does that happen?  Alcohol increases HDL cholesterol (the good kind of cholesterol), has anti-oxidants that reduce inflammation, and has non-clotting properties that make blood less “sticky” and less likely to clot.

What is moderate consumption?  Moderate alcohol consumption is considered 2-3 drinks a day for a man and 1-1/2 drinks a day for a woman.



First patient saved by Penicillin

The first patient who was saved by the antibiotic penicillin was a woman named Anne Miller, in 1942.

The patient had given birth but had developed an infection from the Strep bacteria, and her conditioning was worsening despite surgery and blood transfusions.

Her doctors were able to obtain an experimental drug called penicillin, which had been developed by Alexander Fleming, and injected her with it.  She had rapid improvement and her fever went away the same night.

Anne Miller graduated from Columbia to become a nurse.  She and her husband raised three sons and she lived to age 90.

Her hospital chart from being treated with Penicillin is now in the Smithsonian Museum.
