When something like this happens, things can spin out of control rapidly. Even if it happened in his 60s, he'd be facing age discrimination along with the other barriers to employment that go along with being homeless.

Also, some positions in construction are viable for someone in their late 70s, but the older we get the more prone to grave injuries. My great aunt was cleaning rooms in a hotel well into her 80s until she broke her hip.

It doesnt tell us when he became homeless at all, he could have been homeless for 20 years
