I'm reading a book of Ursula K. Le Guin's essay, which is actually just her blog printed into a book. Years ago, I would have said it's a stupid to print a blog, but it's really way easier to read in that format.
I didn't realize she was incredibly funny. I recommend reading The Sissy Strikes Back
Old age is for anybody who gets there. Warriors get old; sissies get old. In fact it’s likely that more sissies than warriors get old. Old age is for the healthy, the strong, the tough, the intrepid, the sick, the weak, the cowardly, the incompetent. People who run 10 miles every morning before breakfast and people who live in a wheelchair. People who work the London Times crossword in ink in 10 minutes and people who can’t quite remember who the president is just now. Old age is less a matter of fitness or courage than of luck equals longevity.
If you eat your sardines and leafy greens and wear SPF 150 and develop your abs and blabs and slabs or whatever they are in order to live a long life, that’s good, and maybe it will work. But the longer a life is, the more of it will be old age.
