Most people don't have the know how to do this on their own - I tend to follow your advice because you've not led me astray yet, and most of the remedies you recommend are fairly low on disasterous side effects - can't hurt, might help, and I know I don't know what I'm doing!

I do think there is a lot to be said for good diet, exercise, and preventive care which isn't really emphasized enough - many people wait until they're in rotten shape and then go to the doctor crying "fix it!", which isn't the most effective way to handle things.

I do think that people need to make more of an effort to be informed and proactive in their own health though.
