Having around 7500 hours, 75% of it rotary, in a spread of civi and military flying, I made the move to get out of flying totally around ten years ago. I finally came to the conclusion that long term rotary flying 'does your head in'.
Having safely established myself in a new career, though, I do miss flying, from time to time. I therefore make a point of flying planks with a nearby club for a few hours every month. Interestingly, though, I have absolutely no desire to fly rotary again.
I think that, for a good long term money earning job leading up to retirement, fixed wing has a lot going for it.
