Maybe 55 to late 50's would be ok.

I see guys in their mid fifties who are still married with kids and many are still working even in their mid to late 60's or older.

Fuck, I would not want to end up like them! They've always got their hand in their pocket or wallet, the wife wants a new car or a bigger house or a bigger ring ( more carats )

The married guys in their thirties also have these problems, it's just take and take with these women!

These guys mostly wish they had never married and still had freedom.

I'd rather be dead than put up with some nagging and whining self serving bitch for the rest of my life.

I;m not in that position now but being really old still sucks. I don't really feel old yet, but maybe in 10 years time it will be a different story.
