Posted By John Webster According to Richard Hawk's Safety Stuff, "It has been estimated that banging your head against a wall every ten seconds consumes 150 calories in an hour" Can't think how they worked that out, but, on that basis, continuous head banging for an 8 hour day would consume some 12,000 calories, more than a heavy manual labour. So how come I still weigh 22 stones on my more modest diet??

Posted By Descarte Calories as we know them are Kcal's are then not, so I am presuming the actual rate in comparison to your daily recommended intake of 2000 - 2500 Kcal's would be 0.150 Kcal's per hour. Im guessing they omited that for shock effect. I can immagine moving your head banging or othewise every 10 seconds, even though it is pretty heavy would burn so much energy, especialy when I can go to the gym for a good few hours and not even burn off the energy of a mars bar!

Posted By Robert K Lewis Trouble is that calories written as Calories with a big C are kilocalories. So who is right and is there any such thing as right. It could be wrong in a very fetching disguise. Life is one of these things that when you weigh it up there is very little left to enjoy yourself. The gurus are very good at convincing us how to do something effectively but it only seems to work for them even if we follow it to the letter. Witness some behavioural programmes. By the way I should disappear into nothingness every time I join the M1 at Leeds or M42 around B'ham. Bob

Posted By Merv Newman I do not believe that even the most dedicated/frustrated safety person can do a continuous eight hours of head banging. Maybe it just seems like. However regularly combining a bit of head banging with the more aerobic screaming, leaping up and down and the hissy fit thing, rather like interval running, is diagnostic of a serious H&S contender. For maximum efficacity the hard hat should first be removed and thrown to the floor (out of the window is, I find, a bit counterproductive. You only have to go and fetch afterwards) On the other hand, wearing safety boots when repeatedly kicking a door, your desk, or the wall is massively cathartic (satisfying). You can create lots of lovely dents and it hardly hurts at all. Actually punching the wall (with or without PPE) often results in a LTI and could, conceivably, become RIDDOR reportable. Merv (70 kg)

Posted By Peter MacDonald I'm going to listen to Sepultura and some Metallica on the way home tonight in the car and put the headbanging to the test. If i get stuck in traffic will I lose my bear belly? Rock On!!!
