An observation from a lurker re overall health.
As was mentioned somewhere earlier in this thread in order to have robust health you need to be both Physically AND Mentally fit - combined that's what keeps you going.
When either of those are out of balance that's when you get ill.
How many very fit and healthy males are topping themselves currently in the UK from all walks of life? From the basics I know it currently exceeds Cancers and Road deaths for most age brackets.
