Despite my best efforts, I’ve failed to reverse the arrow of time; I continue to get older every day. I don’t feel bad about this—Stephen Hawking hasn’t licked the problem either, and, well, he wrote the book!
You don’t have to be Hawking to know what I mean. Anybody old enough to think about age can probably feel its effects in their bones. And tendons and ligaments and muscles. If you’re a runner (I am... just ran the first trail race of the year today), then you know the saying that goes “it’s not the years, it’s the mileage” isn’t really true. It’s both.
