No regrets getting away from London commuting/management/rat race and retiring at 58.
Plenty of hobbies and a feeling my body was aging and needing more daily rest.
Covid and then buying a fixer-upper house has meant plenty to occupy our
minds, and neither of us have got to grips with all our planned activities & hobbies.
However our new next door neighbours here both retired two years ago. He was 67, active, and has had greater difficulty adjusting. Three unpaid jobs (council auditor, prison inspector, court usher) and took up painting, joined a gym briefly, cycled for a few months; also gets involved with local council activities. Really nice chap, luckily he has a wife, grandchildren and a mother in law needing his attention.
