By orienting your life view to look forward with anticipation rather than tinting your glasses with regrets shaded by activities which may be less possible.

Take a look at KZLRogue who has written here and expresses her pleasure as an Army veteran at resuming combatives such as Karate with doc's permission, resuming golf with doc's permission and the like. Sure, I am no longer a great alpine skier [grew up doing it] BUT there is a handicap program at WinterPark where I hope to learn the use of the recumbent ski. In my case this is because I am severely injured as to nerve function below the knees and no longer feel my lower legs.

Dancing? I can slow and foxtrot with my wife, although faster ones are too much for my brain to handle.

Hiking? Limited by my lower legs, so I no longer hunt in wilderness areas as I did.

Bicycle riding? Oh yes, my favorite, and I used to do 12 miles a day on my mountain bike, so I am working back to that standard with my new bike.

Then there is the professional practice arena, where I have expanded my practice to include New York, working on Texas, plan to form a firm with my sister-in-law and work our way up the eastern seaboard, while also adding California.... why? Because the brain works fine, and the mental challenges are wondrous again.

Just some thoughts,
