To put yourself into a situation where a mistake cannot necessarily be recouped, where the life you lose may be your own, clears the head wonderfully. It puts domestic problems back into proportion and adds an element of seriousness to your drab, routine life. Perhaps this is one reason why climbing has become increasingly hard as society has become increasingly, disproportionately, coddling.
To be seventy years old is like climbing the Alps. You reach a snow-crowned summit, and see behind you the deep valley stretching miles and miles away, and before you other summits higher and whiter, which you may have strength to climb, or may not. Then you sit down and meditate and wonder which it will be.
There is probably no pleasure equal to the pleasure of climbing a dangerous Alp; but it is a pleasure which is confined strictly to people who can find pleasure in it.

I'd like to go by climbing a birch tree~ And climb black branches up a snow-white trunk Toward heaven, till the tree could bear no more, But dipped its top and set me down again. That would be good both going and coming back. One could do worse than be a swinger of birches.
