Too much smoking and a sedentary life-style, I guess. Heredity may have something to do with it as well. But yeah, as far as I know we're pretty close in age. Sept. 29, 1958. Yes, a Libra (fwiw).
August 28, 1959 (Virgo...as if I care). I think it is mostly hereditary Chak. The other stuff doesn't help though. You need to walk or something.
What kind of stents do you have? I know Boston Scientific had some major stent breakthroughs about 10 years ago. I invested some loot in them and did pretty good for awhile.
