The hardest bone in the human body is the jawbone. Intelligent people have more zinc and copper in their hair. The life span of a taste bud is 10 days. The fastest growing nail is on the middle finger. After eating too much, your hearing is less sharp. Your urine will turn bright yellow if you eat too much asparagus. There are more people alive today than have ever died. Women's hair is about half the diameter of men's hair. We are about 1 cm taller in the morning than in the evening. Layers of cartilage in the joints gets compressed during the day. Women blink twice as many times as men do. Did you know any of those or have you more to add?

The skin is the largest organ. I didn't know that about the fastest growing nail being the middle finger. So weird. I wonder why?
