fellis: The human body is an incredibly complex and intricate system and it still baffles researchers regularly despite thousands of years of medical knowledge. As a result, it shouldn't be a surprise that even body parts we deal with everyday have unexpected facts and explanations behind them.
Here are 100 wacky facts about the human body:
1. The brain is more active at night than during the day. Scientists don't know yet why this is.

2. The higher your IQ, the more you dream.

3. Facial hair grows faster than any other hair on the body.

4. The nail on the middle finger grows faster than the other fingernails.

5. Fingernails grow nearly four times faster than toe nails.

6. The lifespan of a human hair is 3 to 7 years on average.

7. The acid in your stomach is strong enough to dissolve zinc. It doesn't destroy the stomach because because the stomach walls constantly renews itself.

8. Women's hearts beat faster than men's.

9. Women blink twice as many times as men do.

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

11. Men burn fat faster than women by a rate of about 50 calories a day.

12. Men get hiccups more often than women.

13. A man has approximately 6.8 litres of blood in the body while women have approximately 5 litres.

14. The largest cell in the body is the female egg and the smallest is the male sperm.

15. During your lifetime, you will produce enough saliva to fill two swimming pools.

16. Babies are always born with blue eyes. The melanin in their eyes needs time to be fully deposited or to be darkened by ultraviolet light to reveal the baby's true eye color.

17. Men have erections every hour to hour and a half during sleep. This is because the combination of blood circulation and testerone production can cause erections during sleep and are a necessary part of REM sleep.

18. After eating too much, your hearing is less sharp.

19. If your saliva cannot dissolve or mix with food, you will not be able to taste that food (try tasting something after drying off your tongue)

Women evolved to have a better sense of smell to sniff out genetic deficiencies in a potential mate, since they had lesser chances of passing on their genes, it was more crucial to them to make sure that whatever partner they mated with was as satisfactory as possible. Women are also better with colors like you said. I am not sure what the reason for this is though I read somewhere that it helped with detecting poisonous fruits and plants (by their colours) while gathering food in the wild. Women mostly gathered food while men hunted.
