Short people of the future?!?

My father's parents were both under 5'5 and had 8 kids who were taller than both of them. My great grandmother was 4'7. We get taller with each generation, but I'm sure it has to do with the fact that when we reproduce, we choose a tall partner. Not hard, as everyone is taller. The shortest female in my generation is 5'2. If I were you, I'd be more concerned with weight than height. Don't let yourself get too thin. It makes everything more difficult.
