My wife pointed out that I can only take a limited appointment that limits me to working less than 90 days per year, otherwise I lose my pension and have to pay back all the pension I have already collected for the year. There would be some hassles with insurance also.
I was in a similar situation. I could work part time (maybe around 40% time). So I did for several years. That gave me something to keep me busy.
But nobody can decide this for you. It's a matter of how you want to spend your time.
Anyway, best wishes as you make up your mind about this. At least you are in good enough health to be able to consider it.
