I retired at age 55 from teaching high school. I was tired of the job and itching to do some other things. I could have gone half time probably with my favourite classes but being tied down was one of the things I was tired of. DW retired at the same time so we were free to travel but didn't actually travel very much. I was in excellent health - the first day of school the next year I spent scrambling up a mountain. I did quite a few interesting things in the next ten years including looking after three of our parents for years at a time. Now at age 66 I'm seriously slowing down. I am very glad I had the decade off work while still "young." I know there are some seniors working that decade who are still feeling young but I think they are exceptions rather than people being kept healthy by work.
We were lucky on the money side by having some savings, pensions amounting to about $3500 a month, considerable savings and inheritances - and good luck in the stock market. It wouldn't be nearly as pleasant short of money in retirement, watching the term deposits diminishing in real value.
