Yup, it was only in cardiac rehab where I learned fitness and health are not synonymous. Always considered myself health-savvy (insert game show gong sound here) until my heart attack at 47. I was a thin, non-smoking gym rat who used to chug milkshakes just to keep weight on. It was a surprise to learn that my good conditioning bore no relationship to the insides of my arteries. Like you, fitness probably did contribute to my survival, though. Some people's bodies seem to make heart disease based on all kinds of factors that have to be managed no matter how many miles we can do.

Sure do miss cheese.
