I am not sure there is a 'too old' really, as there are a lot of older couples where one party will hire a honey trap. I moved area, and began working longer hours in other jobs. I would happily do it again but my partner isn't too keen, and it was always an 'on the side' thing so I just haven't pursued starting again.
As for stripping, there are women (much) older than me doing it, but I feel too old in myself really, plus the club I worked in the most often closed down and I was very 'at home' there, loved the owners, staff and regular dancers. Had so much fun and I just don't think I could find that anywhere else.
Having said that, I really, really miss it and I still dip my toe in now and again. I last worked in a club a couple of months ago and absolutely loved it.
