What’s that about the back Jack?

Man, did my back in AGAIN on Sunday, that’s twice in 6 months. Seriously, I’m really gonna have to do some exercises to strengthen it or something. All’s I was doing was riding my BMX home from work (had to work on the weekend) it was a little cold like 10?c or something and I bunnyhopped up a gutter and click, that was it. So now I’ve got a couple of days off in which I can do nothing other than lie the hell down, Brilliant!!
