A while ago, DS was listening to NPR about a new company called 23 And Me. He basically put it in the back of his memory, useless information kind of thing.
Then he came across a "deal" where the initiation fee would be waived if he signed up for a year @$9/month. He went for it.
The company sent him a swab for his mouth. Upon testing results, he can find out his predisposition percent to inherited diseases...not just the ones he knows.
Also his family origins, etc.
Sounds like fun. You may or may not be interested but here is the link.
