I retired with burnout at 65, having worked full time since I was 18, and having had a weekend/holiday job from 14 years old.
I freewheel I guess but I do have lots of interests (gardening, art, knitting, crochet, embroidery etc, reading and walking my dog)
I have joined a couple of groups so that gets me out one afternoon a week as well as being able to meet new friends.
Ill health means I’m supposed to pace myself (it beats me how you gauge what’s ‘enough’, I tend to not know until I have done too much!)
DH is retired but he has few interests or hobbies beyond going for walks so I tend to pursue solo interests I guess!
