I don't mind work at all; but I certainly enjoy being able to do what I want to do - and when I want to do it.
Well, it's all about what makes you happy. If you like working then there is no reason to stop I suppose, but life shouldn't be all about work.
Retirement doesn't mean sitting in a rocking chair all day. You need hobbies and interests to keep you busy and your mind sharp. If you don't have those then you will just go to seed.
If your financial situation is soild, and will be for the foreseeable future, then you owe it to your self to at least cut back on work or give it up altogether.
But as always, only you know what's best for you.
