Good luck with the new knee Tom. You and I are among the few on this site who remember 1951….lol. It will be 5 years for me on 9/30….but my side gigs means that I’m semi retired. But considering my life prior to 9/30/2020 it feels retired to me. As a life long night owl, I’ve finally experienced 7-8 hours sleep per night. That in itself is life changing.
