Any doctor I "care" about is not making claims, they're busy being a doctor. If anyone is selling something I ignore that site.

I research stuff using the Mayo Clinic site and then dig deeper like with NIH/Government studies (again usually ignoring the places selling snake oil :-)

A lot of "claims" too, come through the Press and medical or science writers too and they aren't professional scientists and usually don't get the whole information out there because they're trying to make it understandable to a lay person so important stuff might be miswritten, etc.

Anything "new" I wait for, no matter what it is, because there's no years worth of experience behind it. I'm not having lasix surgery on my eyes until I'm at least in my late 60s, even though it's "safe" there's no telling how long it lasts and if things can get worse after a few years, etc. I let someone have it for 20 years successfully then have it in my late 60s knowing it will last the rest of my life :-) The knee replacements people have been having; they only last so long, etc. and we didn't know that at first. So people end up "crippled" again only in worse shape because their body is "missing" some of its natural parts now in addition to needing a "second" operation, etc.

If I break a bone you can set it so it heals (which the body does, not the doctor) straight but I'm having enough problems now with one med needing another med for the side effects, etc. already and all for "chronic" stuff that is my lifestyle choices and problems. Thanks anyway but I think I'll lose weight and exercise to get the blood pressure down and other problems related to my overweight self and risk the heart disease a bit longer :-)
