It seems a bit Brave New World, Apocalypse time kinda thing. Like some day, we'll carry our genetic code around like a Driver's License, and the markers will determine what we will or will not be able to do. I've probably read too much dystopian literature or seen one too many SF shows.
It may be a bit paranoid, but it's not beyond the realm of possibility. I guess I just don't want my DNA in a database somewhere. Heck, I don't even like to give out my Social Security number! I think I'll keep my markers to myself.
Still, it is intriguing. Maybe one day my curiosity will get the better of me.
