Saturday Trivia # 2

Some more useless information I stumbled upon.

ANIMALS:

A hedgehog's heart beats 190 times a minute on average and drops to only 20 beats per minute during hibernation.

An average beaver can cut down two hundred trees a year.

An average pig squeals at a range from 100 to 115 decibels.

Average calories burned daily by the sled dogs running in Alaska's annual Iditarod race: 10,000.

Average number of eggs laid by the female American Oyster per year: 500 million. Usually only one oyster out of the bunch reaches maturity.

Average number of hummingbirds required to create the weight of 1 ounce: 18.

Average number of squirts from a cow's udder needed to yield a gallon of milk : 345.

Cats average 16 hours of sleep a day, more than any other mammal.


HUMANS:

During pregnancy, the average woman's uterus expands up to five hundred times its normal size.

Every square inch of the human body has an average of 32 million bacteria on it.

Humans shed about 600,000 particles of skin every hour - about 1.5 pounds a year. By 70 years of age, an average person will have lost 105 pounds of skin.

By age sixty, most people have lost half of their taste buds. (now I know why I can't have just one square of chocolate)

The brain is soft and gelatinous - its consistency is something between jelly and cooked pasta.

The largest cell in the human body is the female ovum, or egg cell. It is about 1/180 inch in diameter. The smallest cell in the human body is the male sperm. It takes about 175,000 sperm cells to weigh as much as a single egg cell.

The permanent teeth that erupt to replace their primary predecessors (baby teeth) are called succedaneous teeth.

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

AND

The Neanderthal's brain was bigger than yours is.

Have a great weekend.
