It was damaged badly enough to be written off for further use, but had not split or totally failed. I have already described the damage. Unfortunately 'Hospital Heros' doesn't seem to be on BBC i player, so you can't look for yourself. A cycle helmet should be discarded after any significant impact, even if it looks undamaged, because the foam will have been internally compressed and will have lost some its protective properties.

Ah yes, that old chestnut. the best that can be said of helmets is that compelling cyclists to wear helmets reduces the incidence of death among cyclists by 45-50%. Given that the root cause of death in cycling accidents can be both head injury (most commonly) or trauma to the body, that figure is quite astonishing, it shows that a simple preventative measure drastically alters post-accident outcomes. See: "The Effectiveness of Bicycle Helmets:A Review", Dr. Michael Henderson [ISBN 0 T310 6435 6] Cue the psycholists whining that Guy Chapman's completely made up statistics trounce any medical study.

But given that drivers over the limit are very disproportionately represented in accident statistics and given the laboratory evidence that over 60mg/100ml people have measurably impaired reflexes, reasoning, depth perception, distance acuity, peripheral vision and glare recovery, there is a high probability that there is a causal link. -- Tony " I would never die for my beliefs because I might be wrong."
