Hi Celticblue.
I'm with you on the gym membership. Mrs PD and me are David Lloyd members, which isn't cheap, but we use it all the time for gym, classes, sauna/spa etc.
Just as importantly, over the years we've developed a circle of friends who attend similar activities as us and this is a huge part of our social life. We'd cut out many other things before dropping our membership.
Good luck you seem to be in very fine shape financially.
PD
