3. Tom Selleck
Long after Magnum, P.I. and his 14-season run on Blue Bloods, Selleck's real passion is a 63-acre ranch in Ventura County that he has owned since 1988. Once a working avocado farm, the land was battered by years of drought that killed off many of the trees, and these days he throws himself into the grunt work of rebuilding it himself. He has said the physical labor keeps him sane, though he has admitted that, with the show over, he needs to keep acting to afford the property. | © CBS Sunday Morning / YouTube
