I retired in March just before I turned 59 in July. The main reason was the job was grinding me down, long hours and inability to take holidays, silly deadlines, evening and weekend working expected etc. and a dysfunctional organisation to boot. Since I retired I have picked up two part time jobs that take up 2 days a week - although I work from home and can work hours / days that suit me. The jobs are much less stressful than my previous job (less money as well though) and obviously working only two days a week and flexibility to work when I want means I have plenty of time to do what I want. My earnings plus pension are adequate for my needs. It is probably the best thing I have ever done, my quality of life is enormously better than it has been for along time. I seriously suspect the decision has extended my lifespan as well.
