More the point, what level of stress was the fellow under. Higher stress level can cause all sorts of problems and it's not hard for the heart to give out under these circumstances. Especially, in those who appear fit and healthy. There appears to be an increasing number of reports of fit and healthy youngsters (in their forties) who are just keeling over for no apparent reason. It is a sad thing to lose a father/husband/son or mother/wife/daughter to such circumstances.
