Thanks for the update milani. I forgot that Fixx died at 52. He was a good writer, an average runner, and appealed to the mass of weekend runners at a time when running was very popular.Fixed died of a heart attack at 52 after running. His family had a history of heart disease. At age 35 he was an overweight heavy smoker. He turned it around, however, genetics and past history can come to collect. And it did.
There are always risks. We can do a lot to minimize those risks, and that's the best we can hope for.
