You had quite a bad accident around the time you got knowledge didn't you, and that probably wasn't the only accident you've had. I know I've had more than one accident. One of them is that classic with losing control of a bale of haywire and having the end hit my chest, breaking ribs. That one is good because I forget all about it and when it aches I think oh here comes the heart attack but it isn't at all. I think we have reached the age where old accidents ache. 
I do feel basically healthy but omg I struggle to get around, I love being able to swim so easily.
It's already like that George Burns quip - I don't bend down to tie my shoelace until I've thought of something else to do while I'm down there.
