That seems to be the case - and actually, that is what molded me. I was a repeat runaway until my grandparents took me in. My grandfather worked until somewhere between 63-64 years old. Planned on spending his retirement hunting and fishing.
He had a stroke a couple years later (not sure if I had lived with them more than a year by then). He did live into his 70s, but it was a severely compromised life and NOT what he dreamed.
I vowed to not have the same thing happen to me.
