In the comments under the Nitpicking post, Lahdeedah mentioned how hard it is to walk up stairs when you're new to the altitude of Colorado's Front Range.

I considered myself a fairly fit fella. Right after we got here, Leonore and I went to the mountains with a friend. Not very high in the mountains, either. I was overcome with the beauty of it all and went running happily along a trail. Born free! As free as the wind blows!

The relationship to writing is a bit tenuous, but it's there. Just like the protagonist of John Denver's great (but often absurdly and unfairly maligned) song, "Rocky Mountain High", I felt freed from my previous life, reborn. I started writing seriously instead of mostly just nattering and whining about it. The following year, my first published short story, "Adam's Servant", appeared in the December 1972 issue of Cavalier, a men's magazine. Brilliant story, of course, but I think they bought it because of the sex. That same issue also contained a short story, "The Mangler", by some kid named Stephen King, who I understand has sold a few more things since then.
