If only a massage and meditation would cure all my health problems.[/quote]
Nope, it won't.
It won't cure my hip, sciatica-like pain etc. Because of concomittant issues yoga, or any stretching based activity, will only exacerbate the pain and do more long term injury.
Pity as I like the solitude and quiet of a good yoga session.
Nor will moderate exercise help my overlarge red blood cells, 2 types of anemia, lack of aerobic fitness, tiredness.
Pity as I like walking, taking the dog out.
Contrary to common belief the only exercise that will benefit me is weight based stuff, weight lifting if I can get to a gym, resistance bands, body weight exercises.
Happily I used to teach just such group classes and have all the kit I need - me and a big elastic band 
I have to explain all of that a lot. I usually end up Top Trumping with my degrees in Health and Exercise and walking away in disgust!
