When you think about it, the way we have organized our working lives doesn’t make sense. We spend the time when we’re feeling our physical best locked away in cubicles and offices. We’re expected to be out of the home right when we’re at child-bearing age. And we’re not released until we feel too old and rickety to do much of anything. Right when our health begins to slide, we lose our employee medical benefits and insurance. In an ideal world, we should retire early, spend our 30s and 40s and maybe 50s enjoying our interests and families, while we still can, and then return to work when we’re old and feel like sitting down anyway.
