I've noticed in the last few years, a growing tendancy to groan slightly when getting in and out of chairs, regardless of the previous evenings activities. I don't suppose this is something that's going to improve with age! The funny thing is, when I'm out on the river and especially when other people are egging me on, I do all kinds of crazy stunts, but when I get home, I do the old "wait till your my age" routine, so that my flatmate makes me a nice cuppa, Hee Hee.
[Pooksad] You are clearly starting to experience the hypocrisy of old age. This is also manufested in the desire to resort to adages ssuch as: "Don't do as I do, do as I say,", and "When I was young..." Keep a note of the symptoms.
