The whole point of my question, admittedly not terribly clear in my original phrasing, was what can someone who's beat up from a life time of skiing and has a genetically inferior spine i.e. pretty compromised physically, substitute for skiing as the number of days forcibly declines from season to season? Most of the classic golden year physical pursuits (golf, tennis, bocce ball, etc.) are off the table. Saying that more strengthening exercise is the place to start, even with physical therapy, unfortunately, is off the table as they may have actually contributed to my accelerated decline with regards to my spine. Please don't say I'm doing it wrong, as I've been doing skiing and spinal focused exercises + PT for many years with very good results ...... until now. I do have several minimally physical activities, but was hoping for something new to experience the wonderful joy and excitement of that addictive logarithmic part of the learning curve.
And, while there certainly are things worse than death, I'm of the opinion that being unable to ski is not one of them.
That all sounds horribly depressing - sorry. I fully expect to be skiing for at least a few more years, and right now it's a beautiful spring day! Pain and infirmity, "I fart in your general direction"!
