Given my missing father, I never developed an identity the way it is meant today. However, I did think my children had the right to know any medical history that might pertain to them and so I am waiting for 23andme to return my spit in a tube results.

Apparently, quite a few people are discovering their father was a sperm donor and they have siblings. One of these says, someone is going to discover, they married a sibling. Shouldn't society be tracking that, and keeping people informed somehow?
