Oh well, I seemed to have got a good growth spurt so I was around 5'3" in 7th grade. I seemed to be above average. I stopped growing in 9th grade. I always thought or dreamed about a growth spurt. I was surrounded by dudes who were getting taller than me. I just thought my time would come, eventually. Good thing I didn't have any NBA dreams.
The only advantage is that muscles look bigger with shorter arms and legs. I don't feel cheated. Most of my relatives are short. I don't think any amount of better childhood nutrition would have changed things.
