"but there are no guarantees. I have a cousin in her early 40s who is a vegetarian and a runner, but recently was diagnosed with breast cancer that has metastasized."

First, let me say I am sorry to hear that, I don't know about you but for me my cousins are like adopted to sisters to me, we are very close.

I think a great deal of health is genetic. We can improve the quality of life with lifestyle changes but I doubt we can do much to change the issue of cancers, heart issues and other genetic based problems with diet and exercise.

I have gone completely off sugar and reduced portions of everything else, especially white flour, and moved to a more vegetable based diet (I love veggies anyway). I have gone from 169 pounds down to 142 and lost 6 inches around the waist (hopefully giving an old guy some appeal with opposite gender ;-) putting my self near the bottom of the suggested wieght table for a guy my height. However I must say that it has had no effect on blood pressure or the way I feel, except perhaps a bit more confident in my clothes! Now if I could just find some way to make myself taller...

One thing I am trying to do: Reduce stress. In all honest, I have tried to reduce my visits to TOD, because I feel many folks are trying to "carry the world on their shoulders". There is much in the world about which the individual can do nothing, and the U.S. is becoming a smaller factor in the world anyway, what we do as a nation has less and less of an effect. I am trying to do things that I needed to do anyway, cut debt, cut waste, save more, etc. At 49 years old however I realize that I am closer to the finish that to the beginning...if there is anything I wanted to do, now is the time to do it, and allowing myself to be worried into ill health won't help me.

This is completely and utterly wrong. Study after study links lifestyle and diet to health. It is just the opposite: many illnesses - including many cancers - have a very strong behavioral/environmental component.

Asian women, for example, on their traditional diets have a lower incidence of breast cancer than "western" women. When they immigrate? Their numbers match the "weigooks."

I'd find you a link, but this is so very well known I think you need to google it yourself.
