“It takes 7 seconds for food to pass from mouth to stomach. A human hair can hold 3kg. The length of a penis is 3 times the length of the thumb. The femur is as hard as concrete. A woman’s heart beats faster then a man’s. Women blink 2x as much as men. We use 300 muscles just to keep our balance when we stand. A woman has read this entire post. A man is still looking at his thumb.”
