I retired at 52 and have never looked back, I had Prostate Cancer and just getting over Bowel, If I had still been working till the right time I would have been too tired to enjoy....... I have been so lucky and just would like for a lot of others to enjoy as we have, however, we did do without previously with the view to getting out early. As for figures...... can't be done, every one has differing values, but, when you are getting low one month I'll bet the car breaks down or the washing M/c packs up............. all this said I would rather be on bread and water than go back to work.
