I live in Uruguay, and the kind of medical checks most of the population has are so superficial, most people who have a heart condition won't know about it until it hits (I haven't had a good checkout in years either !! I should, after reading this).

I know of a case here, the guy was one of 3 managers at a toxic company, the other 2 guys quit, and he took on their burdens. He died of a heart attack, at age 34. He thought he wasn't able to quit because of his children, but the result was obviously worse for them.
