Forgot to tell the "rest of the story". Since many of you eluded to activity in your youth. I started out at 16 years old as a mountaineer, evolved into a hard-core alpine rock climber, taught mountaineering for seven years, never got a real job until I was 30. So yes, I have cut back. Backpacking to me is cutting back. I do mainly off-trail adventure backpacking. As I age, I suspect I will transition into regular trail backpacking. Then transition into having someone else carry my gear. Then day hiking. Then toddling around sidewalks and living in an old folks home. It never stops. When one door closes, just open another.
