139. Hairy

There are as many hairs per square inch on your body as on a chimpanzee. Humans are not quite the naked apes that we’re made out to be. We have lots of hair, but on most of us it’s not obvious as a majority of the hairs are too fine or light to be seen

138. Erection Harness Score

Have you heard of the Erection Hardness Score (EHS) which is used to grade the quality of an erection? The Erection Hardness Score was developed by the European Association of Urology  , and how it works is it grades erection quality based on a scale of one to four.

The levels/grades are:

• Level one – The erection feels like tofu, and the penis is large, but not hard.
• Level two – The erection is like peeled banana, but still not hard enough for penetration.
• Level three – The erection is like an unpeeled banana, which is hard enough for penetration, but not completely, and it is not sustainable.
• Level four – The erection is completely hard, rigid, and able to penetrate easily and sustained for a relatively long time.

According to a recent regional survey done by Pfizer (yes, they make Viagra) in Asia Pacific, many men that experience dissatisfaction in their sexual lives or are suffering from erectile dysfunction usually only achieve a level three erection. The percentage varies from region to region, but the number is a lot higher than you think.

137. 138/year

Greek couples have sex an average of 138 times a year – placing them at the top of the world sex league. Japanese couples have sex just 45 times a year, which puts them in last place

136. Blonds have more hair

Blondes have more hair. They’re said to have more fun, and they definitely have more hair. Hair color determines how dense the hair on your head is. The average human has 100,000 hair follicles, each of which is capable of producing 20 individual hairs during a person’s lifetime. Blondes average 146,000 follicles while people with black hair tend to have about 110,000 follicles. Those with brown hair fit the average with 100,000 follicles and redheads have the least dense hair, with about 86,000 follicles

135. Dreaming

Scientists say the higher your I.Q. the more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register

134. A Woman's Heart

Women’s hearts beat faster than men’s. The main reason for this is simply that on average women tend to be smaller than men and have less mass to pump blood to. But women’s and men’s hearts can actually act quite differently, especially when experiencing trauma like a heart attach, and many treatments that work for men must be adjusted or changed entirely to work for women. 

133. Hair lifespan

The lifespan of a human hair is 3 to 7 years on average. While you lose a few hairs each day, your hairs actually have a pretty long life providing they aren’t subject to any trauma. Your hairs will likely get to see several different haircuts, styles, and even possibly decades before they fall out on their own.
