To be honest I don't want to stop working.

I think once you stop working you start dying. I wouldn't like a survival job at that age, that'd be hell, but working for myself even if it's taking care of a small farm or anything that keeps you busy and gives you the chance to solve daily problems.

Sitting on a bench after retiring until I die is not an option.

I think it's a mixed bag. My parents are divorced, but are on the opposite ends of the spectrum here. My mother is extremely ambitious in her career, and maximizes out her retirement contributions every year. My father is quite the opposite, and I don't think he's made any plans when it comes to handling retirement.
