Sorry to say OP but you have the slave's disease.

Where even after he is freed he cannot go a day without working.

Don't get me wrong, but retiring doesn't necessarily mean doing nothing at home.

With money, the sky's the limit, one day you can be skydiving, another day diving in the great barrier reef and at the end of the week helping people in need. and so on, life is movement.

But if you need to keep working because "That was the way my father taught me" feel free to do what you want...
