Well I am about 6' and I see no advantage to height most of the time. Generally shorter people live longer and enjoy greater health although there are some serious conditions associated with being extremely short. Still I'd rather be 4' and avoid enlarged hearts, overworked organs and greater susceptibility to industrial accidents. Plus I really hate basketball and I know people would constantly ask if I play.
There is this game that these hmong (I think) guys play in the park. It's kind of like volleyball but they play with their feet. It looks awesome and all the best guys seem to be around 5 ft. I'd love to be able to move the way those guys do.
