I've avoided this thread until now. But here's my take: I had a chance to do this in a limited way this winter. Took an 8-week ski tour out west on my own, visiting 14 different areas. I could have skied every day I didn't travel. But what I found out was that no, I couldn't -- and didn't want to -- ski every day. As a background, I'll say that when I skied, I skied fairly hard. Average was about 25K vert/day -- some more, some less -- often off-piste. But, at 62 with some history on my body, my knees and other parts just couldn't sustain it. I needed time for rest and rejuvenation. So I came to feel like I just couldn't ski everyday b/c my body would break down. Secondly, skiing too much limited other things I wanted to do. Even though I was on a ski excursion, I wanted to be able to sleep in, do errands, visit with my daughter, etc. And finally, I came to feel like Phil: too much of a good thing reduces the specialness. I wanted my skiing to feel like a gift -- not a job. So finally, I conclude that, even given the opportunity, I couldn't ski every day.
Just my $0.02.
