Do you ever have the feeling, assuming you are 50+ like me, that life has flown by, and what remains is a gradual slide into decrepitude as one's body and brain gradually fail?
We were talking about this a couple of weeks back, and I said that if possible I'd live the same life over again, experience the same things for the first time, even without the experience and wisdom I've collected on the way.
After Sarah's death it needed a deliberate decision for us to stay together, not because we'd fallen out about anything, but because the natural desire is to escape, move on, start again. The aging process causes something similar I suspect, a greiving for lost youth and strength. It's no surprise that middle-aged men leave their wives and families of many years to attempt to recover what they've lost, and all the sharp-tongued comments about the manopause and old men in sports cars only makes me feel more sympathy - though not agreement - toward them.
My grandfather had grown up in a world where older men of his background were respected for their experience and survival (to acheive 70+ in a working class environment was good going) yet was disappointed that, when it was his turn, no-one cared. The present world cares even less for 'old people', though rubs along with them them if they can still afford to live normally. While I'm maudlin like this, the future isn't orange.
