I'm 65, retired. I'm more physically prepared now than when I was younger and busy with work and kids. I have time and money now. I see plenty of other backpackers in their mid 60s, but hardly any backpackers in their 70s. I've been doing a lot of backpacking in recent years because I know my time is running out.

I just got back from 11 days hiking in the Grand Canyon. My left knee hurts, so maybe time is running out...
