Don't think I know many from my working life that would still be do those jobs coming up to 70 . . in fact I'd guess 60 would be a push before leaving and finding something less demanding on the body.

Then you have the problem of actually finding another job at that age, where even the dumbest jobs are taken by the 'younger' ones because a 17yr old on minimum wage is paid less than an older person.
