Getting back to Michael Phelps also mentioned in the show he too has some kind genetic predisposition that gives him an edge. Apparently not widely known outside of the sports world or at least its the first I heard about it.

Hardworking muscles release lactic acid, which causes soreness. But Phelps' body can flush out lactic acid in minutes vs. the hour or two it takes the bodies of most athletes.
So this brings up some interesting questions. Is it fair for someone like that to compete in Sports? I think the answer is absolutely yes the bigger issue in the future is going to arise where you'll have regular athletes abusing this information and science will be able to produce stronger and faster athletes not through the typical steroids but through manipulation of natural means or even DNA.
For example the 3 year old toddler was being examined by doctors in the hopes that information could help in a cure for muscular dystrophy. On the flip side of the coin suppose they cure MD but some kid comes out of it much stronger than he normally would, Does that disqualify him from Athletics?
Just some food for thought but I can see this being quite controversial in the future.
