I started this thread in chat but thought I'd give it a go here as well.
"I just had a good look at my knees, omg they are all funny shaped and wrinkly. And my elbows too.
What to do, is this it then? 43 years of bending and they're buggered never to be shown in shorts again?
Please please, if you have rescued your knees and elbows back from the brink, tell me your secret!"
