My family's height is all over the place so I came out to an even 5'5. (Im a woman)
Interesting. Human height is measured from the bottom of the feet to the top of the head. My family is generally tall and I am 6'1" (male).
6'1 is a very good height! My ex-boyfriend was 6'2. How do you feel about the discrimination against short men?
I don't think shorter people should be discriminated against. However, height can be an indicator of nutritional quality and health.
Agreed. I don't care what people look like as long as they're healthy. You only have one life.
Height can also be determined by environmental factors. People living in certain areas tend to have similar heights.
Very true. I imagine in heavily dense forest areas people are taller. But that is purely an inference. 
I would not be surprised if that is true. Certainly height would help them reach tree branches easier to escape predators.
