Can I laugh at Mich Jagger?

An excerpt from the amazing book I stumbled across:

"I'm in my late fifties now. When I was young, I never imagined the twenty-first century would actually come and that, all joking aside, I'd turn fifty. In theory, of course, it was self-evident that someday, if nothing else happened, the twenty-first century would roll around and I'd turn fifty. When I was young, being asked to imagine myself at fifty was as difficult as being asked to imagine, concretely, the world after death. Mick Jagger once boasted that, "I'd rather be dead than still singing 'Satisfaction' when I'm forty-five." But now he's over sixty and still singing "Satisfaction". Some people might find this funny, but not me. When he was young, Mich Jagger couldn't imagine himself at forty-five. When I was young, I was the same. Can I laugh at Mick Jagger? No way. I just happen not to be a young rock singer. Nobody remembers what stupid things I might have said back then, so they're not about to quote them back to me. That's the only difference."

This is from Murakami's "What I Talk About When I Talk About Running" and all hyperbole aside, I feel a little like this book is saving not my life, but my potential life.

I am savoring this thin little book and will definitely write more about it when I have absorbed every last word.
