(Virtually) no-one dies of lifestyle-related cancers at 35. I still wouldn't want to die of cancer or heart disease at 60-80 (my grandmother was very unhealthy, had her first heart attack before 65, and died at 72), but I think dementia is a scarier prospect (my great grandmother died at 96 but had dementia for at least a decade before that).
