My brother skipped a grade in elementary school, graduated HS at 16 and although a very good athlete for is age never played sports in HS because he was too small and younger then everybody. He graduated College in 3 years while still only 19, I always thought he had an unfair advantage over other kids his age because he had two years work experience before other kids his age graduated college. While I am sure if he had it too do all over again he would give up all the money and success he has to just get that extra year of HS lacrosse.
