My co-worker was a consistent runner. His log showed 6 days short of 17,000 days running at least 5 miles. Some days were marathons. The record broke with a sprained ankle from playing wallyball. The day he died of a heart attack at age 44, he had biked 15 miles to work, ran 5 miles at lunch, played wallyball after aork and biked 15 miles home. Fitness is no guarantee. His father died of a heart attack too.
Everybody knows you shouldn’t play wallyball after aork - aorking takes it right out of you!
I am NOT trying to be funny but maybe the excessive exercise was a factor.
