Im pretty sure we all ask ourselves on occassion - "will my training kick in when I need it most?" Usually the 'when you need it most' times are when you have no time to think about it and hope that what's been learned is instictive enough to work when it matters. Seems reports Ive read here and elsewhere indicate that it does happen when it matters.... Just experienced such a case..
Falling can kill. Nothing made this more apparent than the high profile tragic case of cricketer David Hooks last year. One punch in the head, probably fairly benign in itself, knocked him over and he hit his head on the ground with terminal consequences.
I walked into the laundry and the washing machine had flooded the place out. Took one step on the tiles and went the proverbial bum up. We practice falling, even incorporating it into the warm up (its a great way to get to the situp position

), and in a flash I found myself on my back, chin tucked into chest, but still rather sore (more practice needed

). I have no doubt that but for this I may have been in a bit of trouble.
Learn to fall....
