One of my warmshowers guests was an interesting guy, about my age at the time, in his mid-50s. He was a single father who'd gotten his son through school, then quit his job and dropped off the grid. He'd been living on his bike, doing some serious cycling (5-8000 miles per year) with decent gear. His yearly budget was $5000. He was challenged one year with a broken collarbone. He was happy, had all his teeth, was clean, and looked good. He'd found a few places he liked to settle down for a season once in a while and make a little money as a skilled carpenter. He said he had a bit of a social media following as well, but I'm not into that and didn't pay attention.
