I think it's shifted upwards over the years. I'd say 40-65 now, whereas 30 years ago it was more like 35-60.
Taking life expectancy to be 75.... young is 0-24, middle-age 25-49 and old is 50 upwards.
Bollocks, I've been bumped out into the 'old'
If I was actually bothered about age, it might worry me but I am not. Time goes on. Despite my prodigious intellect and powers, I haven't found a way to stop it yet. I will keep trying and let all of you 'young' people know when I succeed so that you can stop worrying ... or start.Personally, I don't think the time that's passed since you were born is as important as what you've done with it.
I've had my ups and some significant downs, but I'm probably the most content now than I've ever been in my life.
