I am friends with a couple, she is 50 and he's 65. My girlfriend has always been very young-minded, active, trendy etc. but in the past two years she's let her hair grow grey, cut it short, joined activity groups for older people, moved with her husband into a retirement complex and has an attitude of "I'm old, I'll say and do what I want". Both still work in good and enjoyable jobs but aspire to be retired and get positively envious of people who retire early and travel the country in a camper van.
I'm more of an age with her husband but find myself drifting away from them because I can't stand this grump old pair they're turning into. I wonder if it's because I have young family that keeps me young but at some point, I'll also "turn".
