Maybe work less? I know four people who died of heart attack. Two of them were in terrible shape (obese, no exercise), while the other two were in very good shape, but were also workoholics in stresful jobs. One of them even got the attack while jogging in the park (he collapsed in a rarely frequented part of the park and was dead before anyone noticed) He was a CEO of a decent-sized company in his early fifties.
