During the time when I was between 64 and 80 years old, my wife and I have bike toured over 22,000 miles, about a total of 2 years, in 11 different countries. This included several short seasons or cancelled tours due to Covid, shoulder surgeries due to a skiing crash and a bike crash, and a broken leg while telemark skiing last April.
We also do a lot of training/utility/recreational rides. My wife's "new" 10 year old touring bike has over 28,000 miles on it. It is her favorite, but she also rides 2 other bikes, a road bike and her old touring bike.
The point of all this BS is to keep going as long as you can. I plan to keep going until I can't remember where I parked my bike.
