The only problem with it is so many people post questions asking for medical advice, and even if you were qualified to give that advice, you don't have nearly enough information. Aside from telling them to see a doctor there's no much you can tell them.

This section imo is really useful, because people would ask ?'s about eating habits, personal diet, ?'s about certain foods/drinks, etc...
...and frankly there was no section for that. Therefore the health section did address that "gap" in the question asking on this site.
However, I agree with "candlewax". This section is good to bounce ideas off of each other. I remember one ? a girl asked about how to eat healthy for cheap, and ppl, including myself, were useful for that. But this site is by NO MEANS a substitute for seeing a doctor or using a site like WebMD that has legitimate medical advice and information.1
