Obviously a very interesting guy, and raising a family, wrestling with this question personally and professionally.
It made me think quitea bit, about how that question has changed for me over time. Turning 70 in a few months, I know I want to be in, and around, big mountains, but I also know my appetite for risk has changed considerably, and is now quite low.
If I hike or skin up to an alpine hut, and the vibe isn't right, I have no problem staying put, eating strudel and drinking tea, and heading back down in the valley.
