I found this picture on the creaky joints page some time ago and printed it off and I refer to it on those occasions when I am being too hard on myself for not doing all the things I think I aught to be doing or when I am getting frustrated with it all - it reminds me that all things are transient and sometimes it's better to just sit them out rather than fighting them or trying to change the things that I clearly can't change....
I hope your personal storms pass soon and more sunny climes come your way soon.
All the best
Ali
