The Human Body - part 3

Continuing a fascinating list of facts about the human body, here are another 10 curiosities that are just as mind-boggling as they are peculiar:
21. The three things pregnant women dream most of during their first trimester are frogs, worms and potted plants. Scientists have no idea why this is so, but attribute it to the growing imbalance of hormones in the body during pregnancy.

22. The life span of a human hair is 3 to 7 years on average. Every day the average person loses 60-100 strands of hair. But don't worry, you must lose over 50% of your scalp hairs before it is apparent to anyone.

23. The human brain cell can hold 5 times as much information as an encyclopedia. Your brain uses 20% of the oxygen that enters your bloodstream, and is itself made up of 80% water. Though it interprets pain signals from the rest of the body, the brain itself cannot feel pain.

24. The tooth is the only part of the human body that can't repair itself. 25. Your eyes are always the same size from birth but your nose and ears never stop growing.

26. By 60 years of age, 60% of men and 40% of women will snore.

27. We are about 1 cm taller in the morning than in the evening, because during normal activities during the day, the cartilage in our knees and other areas slowly compress.

28. The brain operates on the same amount of power as 10-watt light bulb, even while you are sleeping. In fact, the brain is much more active at night than during the day.

29. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Neurons continue to grow throughout human life. Information travels at different speeds within different types of neurons.

30. It is a fact that people who dream more often and more vividly, on an average have a higher Intelligence Quotient.
