After 6 years of retirement now, there is no doubt that this has been true for me. I will say, though, that you have to plan in advance for what you will actually DO in retirement (how you will spend your time), before you leave the working world. I thought about it a lot in the years leading up to retirement, and I have had no problem keeping myself occupied, doing things I enjoy. As for the health aspect, my health has definitely improved since retirement, mostly due to having more time to cook and eat healthier meals, exercise more, and of course lose some of the stress associated with working. But, again, you have to be willing to put a little effort into it, especially with regard to daily exercise. You don't need to go to the gym every day (or at all, really), but you need to stay active in some way. For me, daily exercise is so ingrained now that I would really miss it if I couldn't do it for some reason.
As I've said in other threads, taking care of my health is my "job" now, and I am my own boss, which is great.......
