If your body keeps getting older, then hell no. What would be the point of that? So I can be an old man who can't move for a few billion years?

No way.

If your body stays the same, then no anyway.

The next generation of people after that would be broke, lazy, etc. because there would be no room for jobs, and they could just live off of what their parents make for a few billion years.

If you motherfuckers will stop always worrying about yourself, then you'd realize everything is cycle based. You can't screw it up so you can live longer.
