As a user, there is zero chance I'd be comfortable with uploading detailed health information about myself anywhere. That's just too sensitive and personal to share. I'm also not convinced that such a database of information would be terribly useful, at least in the US. Although I don't know, I'm totally open to being corrected here. What decisions would I be able to change based on it?
