Weird Facts about Humans (2)

Earwax production is necessary for good ear health. While many people find earwax to be disgusting, it’s actually a very important part of your ear’s defense system. It protects the delicate inner ear from bacteria, fungus, dirt and even insects. It also cleans and lubricates the ear canal.

Babies are always born with blue eyes.  The melanin in a newborn’s eyes often needs time after birth to be fully deposited or to be darkened by exposure to ultraviolet light, later revealing the baby’s true eye color.

Every human spent about half an hour as a single cell.
After eating too much, your hearing is less sharp.

Women are born better smellers than men and remain better smellers over life.

Your nose can remember 50,000 different scents.

Nails and hair do not continue to grow after we die. They do appear longer when we die, however, as the skin dehydrates and pulls back from the nail beds and scalp.

By the age of 60, most people will have lost about half their taste buds. Perhaps you shouldn’t trust your grandma’s cooking as much as you do.

Your eyes are always the same size from birth but your nose and ears never stop growing.

By 60 years of age, 60-percent of men and 40-percent of women will snore.

Monday is the day of the week when the risk of heart attack is greatest.  A ten year study in Scotland found that 20% more people die of heart attacks on Mondays than any other day of the week. Researchers theorize that it’s a combination of too much fun over the weekend with the stress of going back to work that causes the increase.

Provided there is water, the average human could survive a month to two months without food depending on their body fat and other factors.

Over 90% of diseases are caused or complicated by stress.

A human head remains conscious for about 15 to 20 seconds after it is been decapitated. While it might be gross to think about, the blood in the head may be enough to keep someone alive and conscious for a few seconds after the head has been separated from the body, though reports as to the accuracy of this are widely varying.

Babies are born with 300 bones, but by adulthood the number is reduced to 206.

We are about 1 cm taller in the morning than in the evening.

It takes twice as long to lose new muscle if you stop working out than it did to gain it. Lazy people out there shouldn’t use this as motivation to not work out, however. It’s relatively easy to build new muscle tissue and get your muscles in shape, so if anything, this fact should be motivation to get off the couch and get moving.

Tears and mucus contain an enzyme (lysozyme) that breaks down the cell wall of many bacteria.

It is not possible to tickle yourself. Even the most ticklish among us do not have the ability to tickle ourselves.

The width of your armspan stretched out is the length of your whole body. While not exact down to the last millimeter, your armspan is a pretty good estimator of your height.

Humans are the only animals to produce emotional tears.

Women burn fat more slowly than men, by a rate of about 50 calories a day. Most men have a much easier time burning fat than women. Women, because of their reproductive role, generally require a higher basic body fat proportion than men, and as a result their bodies don’t get rid of excess fat at the same rate as men.

Koalas and primates are the only animals with unique fingerprints. Humans, apes and koalas are unique in the animal kingdom due to the tiny prints on the fingers of their hands.
One human hair can support 3.5 ounces. That’s about the weight of two full size candy bars, and with hundreds of thousands of hairs on the human head, makes the tale of Rapunzel much more plausible.
