I do have a grumble once in a while but mostly just accept there are things we can't do. We're both fairly resilient if nothing else. :)
Sore knees are bad enough Malcolm ..as are all things that affect people's health. From reading this thread, we all have our crosses to bear.
It's surprising that, when you talk to people who look OK and are getting on with life, just how many have their own health stories to tell.
