I think it's a complicated subject, too complicated to generalise.

Who know what the reason is? Many years back, I worked for a bloke with 3 sons, two of them had their own separate successful company, plenty of work, no company debts.

Suddenly, one of them went off and hung himself. Married, children, no marital problems, no money worries, got a nice car and a house as well and everything going for him.

What struck him to drive off, walk in to a wood and string himself up? No-one could fathom it out. I suppose there's a lot like that? Sudden feeling of hopelessness at many more years before them?
