OK, so the 21 bit is a lie (looks better than the real thing though) but the rest of it is true.
I was moving my everyday bike (mtb with baby seat) from one side of the garden to the other, not even fettling FFS, and somehow put the bike down wrongly. The chain ring has removed a very deep chunk of my lower shin.
I looked at it, and could see a lot more of the inside of my leg than is a good idea
, went very hot and wobbly, and phoned for Mr F to come and help. I now have 3 stitches and 3 steristrips holding my shin together; Mr F didn't do that (wrong kind of doctor) but he did take me to A&E and kept an eye on M.
I would post photos but there is no way I'm taking the dressing off yet, and anyway my legs are a bit hairy.
