Sister a future Olympic swimmer?

[cakesinacup08]

Hi! I just had a quick question for anyone who knows about the freakish proportions of Michael Phelps...My older sister is 19 and has always been the athlete of the family. She was an awesome volleyball player and had now taken up swimming in college. She has always been self conceise of her body because 1.) She is 6' tall and 2.)Her proportions. I just read an article by NBC about Michael Phelps and his body and I just wanted to see if my sister sounded like him and if I can boost her confidence just a little so here it is: She is 6' but has a 6'2" "wingspan, her torso is 3/4 of her body and her legs are that of a 5'6" woman. Plus, her knees are double jointed. Could she possibly be a future olympian? Also, she swims at least 3 hours a day 7 days a week and beats most of her male counterparts....hope you can give me some straight answers and maybe make her a little more comfortable in her skin!
