I think this pretty well sums it up for me. I'm 78 and was being stressed by a cataract while driving at night, that condition has been corrected and stress removed.
I believe that age is a state of mind, I admit that physically I'm not as strong as I once was. Do I plan on doing 600+ miles a day? Absolutely not, is 300+ a day doable? I would think so and I'm going to keep at it until mentally it is not comfortable.
The quote at the beginning of this reply says it all.
