There are so many good people in the world! I can't imagine how interesting it is to meet people from all walks of life. The Airbnb we used to stay at in St. Thomas had a lot of spaces we shared with other guests and breakfasts were sometimes communal. We met several interesting people during our short stays, a few of which we're still connected with online.
Some day we might decide to become hosts ourselves but, ideally, I would want to be in a milder climate that we're in now. I can't imagine spending our retirement years in the Siberia of North America!
You and your wife would make perfect hosts, you should seriously consider it! Move to a warmer climate (Siberia!!!) before all the aches and pains start, and get a property with Airbnb potential😉 Maybe closer to your family?
I'm sorry we did not do this as soon as the kids fled the nest.
