Scott,
that's a shame, but you've got to do what is best for you and your loved one's.
As much as I consider myself priviliged to enjoy the job I've been doing for 25 years, I know that now, I am just a number and not a name and if I could afford to retire, I would.
If a quirk of fate hadn't turned in my favour, I may well have been doing a job I hated for many more years and for a lot less money.
Enjoy your retirement, all the very best to you and keep in touch.
