DNA Swab for kids athletic Genes?

I just heard about this DNA swab for athletic genes people are starting to use to see if there children should play sports and which sports they should play.

What a crock of feces that is. So you are telling me your gonna tell me what I am good at if anything at all. What ever happend to sports being a way to teach kids about commitment, hardwork and determination. Wow if people except this it will blow my mind, this is unreal so If I didnt test for explosiveness and speed I should try golf hmmm anyone ever golf with me”it aint pretty”, but I try and practice to improve I dont just go get swabbed and say ahh guess it isnt for me. 

I wonder if I was swabbed when I was a kid what my outcome would have been. Cause I can tell you as a kid I was clumsy uncordinated and not exactly a star athlete. In a time when more and more children shy away from sports, for computers and video games lets push them away even more. Lets not instill work ethic and determination in the future of the world lets encourage the easy way out.

I wonder others thoughts on this swab idea?
