Is it worth it, nope. If you actually got any benefit from knowing your genetic conditions you were more pre disposition to then insurance companies would offer it to you for "free" to improve there screening process (or they could be purchasing that data from 23andme). But really knowing you are 20% more likely to get breast cancer are you going to start getting more breast exams, or just keep on living life? Plus a couple months ago HN had a link to a news article where they sent there DNA off to multiple companies that do DNA testing and had mix results across the board. Companies like 23andme are only as good as the database of DNA they have. You will always get mix results because comparing DNA falls into NP where you can not improve the time it takes to compare DNA. You will never get a full picture of you DNA from a service that only charges a few hundred bucks. It is like paying $10 a month and expecting a CDN at google scale.
