Not posted for a while, but here's my 2 penneth. I'm 59, still on ladders and doing 5-6 days a week. I'm still in reasonable nick, although I've put some pounds on over the last year due to the lockdown! I have no plans to fully retire, but there will come a time when I will cut down to maybe 2-3 days a week. I have a good number of shop fronts that I do, so I will keep those and cherry pick which residentials I will retain. My son and daughter work with me, so when I cut back they can take the rest of the run over.
