In reply to CJD:
In my younger days <wise old sage voice> I used to be a mountaineer, it was a place I needed to be. Rockclimbing was just training for the real thing. I was quite disparaging when even talking about it. Dismissive even.
Living in th UK for a while made me have to rockclimb but I wasn't really into it. That came with time at Smith Rocks, a month in Yosemite,Squamish, Fire rock shoes, a month in Arapiles and realising how much time I spent being wet cold and miserable or stuck in a hut while back on the lower levels the sun shone and there were new crags opening up. One pushy alpine climb had me questioning why and if this was why I originally started doing it so I stepped away from Alpine climbing something I never thought I could do.
So rockclimbing became a major focus with the assistance of a government climbing grant for a while. New routes all sorts... fit climbing well etc.
Somewhere along the way a bit of real life kicked in. Grades plummeted (annoying since most of my peers are climbing teh same or harder than they did 10 years ago). The mind games set in.
I suppose now I am up and down. Quite involved but I don't NEED to climb to anything like the same extent. I do but I think I could let it go. But I suspect I would have some involvement in some way still even if not as actively.
Like CJD though I think losing my sight - ability to read/photograph would be harder a challenge for me to accept.
