about 10 years ago I posted the question about this topic. I was in my early 60s and was wondering if it was all worth it (including getting a new rifle) if I only had a few years to hunt. Thankfully I was persuaded that yes, I had enough time left so I got Steve to build me a 7x57 (which I love) and hunted with my son-in-law and my #2 son until prostate cancer surgery stopped me until last year. Now at 74 I start to ask myself the same question, how many years of hunting left? What I determined is that I'll be damned if I'm going to let a few medical issues stop me and I can see hunting until at least 80 although I might let the boys help with the heavy lifting. We used the first round of stimulus money to get a Nordic Track treadmill and I have set a goal of being fit enough to do some decent stalking and walking by the fall. Your mileage may vary.
