23andMe, founded by the wife of one of the Google guys, is basically a comprehensive personal DNA test. There are other services that do this, but this is expected to be the most comprehensive (I believe). If your curious what type of information you will get from it, Mark Fletcher (the founder of GoDaddy) describes his results here. The process isn't cheap, $1,000, and it brings up the question of how much do you really want to know about your future (are you going to live life shattered if you know you have a high likelihood to become sick later on in a certain way), but it's the information could be really interesting. Some of the sample questions that might be answered are:
- Do your genes help you sprint faster?
- How well can you taste bitter foods?
- Do you share maternal ancestry with outlaw Jesse James?
- Are you more similar to Mayans or Basques?
