Spent most of 2023 trying to get heart issues diagnosed and then fixed, still working on that last. Was finally able to start riding a few weeks ago and that's going well, better every week, but still a long way to go before I'll be strong enough to ride all of my hilly local routes on the tandem. I was essentially off the bike for a year, so this is to be expected at my age. I have what I hope to be my last heart procedure at the end of December. Things should get even better after that, 98% chance of survival. Looking forward to '24.
