Brad, have an acquaintance who took up boat building after he retired and built several in various locations; he and his wife migrate between several homes, though they aren't wealthy. Some of the boats were small and one or two were pretty big, with cabins and engine compartments. After some stents, he took up oil painting. He's gonna do something, whatever's possible. Hope you find a niche activity or two that bolster your health. Take it slow and find out what works for you.
