bs0d3 writes "Parents are being sold on the idea of buying DNA tests for their kids, to find out which sports they will be better at. The company called Atlas is based in Boulder, Colorado; and is selling DNA tests for $160. They are looking for what's called the ACTN-three gene, the gene behind what is called 'fast-twitch explosive muscles.' Children that don't have ACTN-three will be better suited for endurance sports like long distance running or swimming. Children that have a lot of it will be better suited for sports like football, rugby, wrestling, or hockey. Kids that have some ACTN-three will not be the fastest and not the slowest, they don't burn out the quickest and they don't last the longest. They are categorized as capable of playing just about any type of sport they like."
