I'm in my early 70's and although I have not needed hip surgery (yet) I can definitely notice I'm slowing way, way down on my hikes and backpacking trips and I can't carry quite so much in my pack. I just take note and adjust. Next week I'll be spending about 8 days in and out to Mt. Whitney using the Cottonwood pass route. This is my third backpacking trip on that route although I haven't made it all the way to the peak. But I'm going to give it a real good try this year.

Don't let the age thing get in your way and adjust for whatever physical challenges you might have. Just enjoy God's creations the best you can.
