Absolutely! I am at that age where, if i don't keep the joints and muscled loosened up pretty regularly, I am asking for trouble. Fortunately, I live in a state that has an abundance of public lands and hunting opportunities for a number of species year-round, so it is pretty easy to get out two or three times a week to get that exercise.
Also, being retired gives me the flexibility to choose when and where I want to go. I can choose flat, desert walking, high-altitude, straight up and down mountain hiking, and pretty much everything in between. ...In recent years, the "flat, desert walking" seems to win out more often than the others.
