"I think that what you need when you retire is a job that isn't a job," said DH when we were planning our individual retirements. And we did just that, with the organisation to which we both belong - Rotary International (in different clubs, I hasten to add) and others.
I "worked" for quite some time as an Ambassador for Cancer Research UK, talking to groups and fundraising, and DH "worked" as Chair of the moderating board at the Young Offenders Institute.
We have slowed down a bit now, but he still goes off cycling every other day (does about 26 miles!!!) and I do a bit of mediation work.
That suited us - we could not live in each other's pockets. But then, the first twenty or so years of our marriage were spent in the Armed Forces, where one had to be able to cope independently.
