I get the sentiment! Hindsight is 20/20, right? Taking care of ourselves can often take a back seat when life gets busy. But hey, it's never too late to look into new options that might help improve our well-being. Since you mentioned arthritis, have you ever considered trying CBD? I recently read that CBD offers relief from back pain and can have anti-inflammatory properties that might help with arthritis as well. While it's not a cure-all, it could be something to consider adding to your existing treatment regimen, especially if you're struggling with pain. Always a good idea to consult your doctor first, of course.

I also would have thought twice before breaking my arm, leg, back, skull, toes, feet, hands, and fingers. I was only medically checked for 3 of my breaks, although I knew of more, but as the arthritis sets in, I discover new ones that I didn't know about.
I've tried many things over the years. My college days of running, triathlons, and bicycle racing did a number on my knees. It had been so bad several years ago, I could hardly walk, until everything loosened up. Then, if I sat for a while it got bad again. I started taking Glucosamine (Osteo-Biflex) and Tumeric w/Curcurmin(Schwartz). Both are over the counter, and I buy on Amazon. On the suggestions of an Orthopedist, who said it could help. She said if it didn't, then strong anti-inflammatory meds would be needed. Literally overnight, all pain disappeared. Several years later, everything is perfect, no flair ups, and my knees feel 30 years younger. A couple other co-workers had similar issues, to the point of knee replacement, and they have been great for a couple of years. I'm not saying it will help everyone, but, since I still have good cartilage, it was a Godsend.
Glucosamine works for some but not for others. I've heard the claim that its success is mostly the placebo effect. OTOH, we had an Irish Setter with with serious arthritis and we tried giving him the glucosamine, mixed in with his food so he wouldn't spit it out. It didn't make him frolic like a puppy, but it did improve him enough to let him move around normally. Stairs became possible again. Since I can't believe in a canine placebo effect, I figure it worked.
Glucosamine alone didn't do much of anything for me. But, when combined with the Tumeric, it was like a miracle.
