I can't wait to give up work. I'm 52 and have been planning what to do with retirement since I started work really. I don't hate what I do, and have had some great jobs.
But...there's so much more of the world I want to see than can be managed in annual leave, I want to garden, read books, do more exercise. I'm well paid, in a secure interesting job.
My husband on the other hand can't even imagine what he'll do when he retires, his identity was for years tied up in his job, not so much now in a new job, but working is still integral to his sense of self.
