People should have ready access to the information to make a cost- benefit decision regarding helmets. If the costs are soooo minimal, and if there is any benefit whatsoever to be derived from helmet use (or, if there is simply no reduction in safety due to helmet use), people should know this. Then, the choice should be theirs. I know you're wanting to ignore statistics, but I'm afraid we can't do that. Statistics are the ONLY way to tell what benefits of helmet use. Otherwise, we have to rely on speculation and anecdotes. Logic 101 should have taught you the weaknesses there. Regarding costs and benefits, a large study was done to evaluate the costs versus benefits regarding helmets. Actually, it was the cost to benefit ratio of Australia's all-ages mandatory helmet law. "An Economic Evaluation of the Mandatory Bicycle Helmet Legislation in Western Australia" by D. Hendrie et. al. Briefly, it indicates that the helmets, or the helmet law, were probably not worth the expense. There was some uncertainty in the findings, but they figured the outcomes ranged from a possible benefit over six years of $2 million, to a possible detriment of $10.5 million. However, they point out that their figures do not include the losses to public health caused by the very significant reduction in cycling that came with the law. In other words, that legislative experiment was a failure. Not that the legislators are likely to change it, though. It takes a lot for a legislator to say he was wrong! Now, the same principle holds closely for helmet promotions. The more people push helmets, the more money is spent on them. But the reductions in head injuries don't seem to appear as promised, except perhaps by dissuading people from riding. And I can't accept a strategy that protects cyclists by encouraging them to give up cycling! Back to Stephen Harding... (I'm trying to learn proper posting here. Is it working?) Focusing only on the dangers to one's head on a bike seems a negative portrayal of the activity to me. Three answers: 1) This _is_ a bike forum. I tend to think that focus on bikes is appropriate here. But the _only_ way to rationally evaluate danger is by comparison with other activities! In threads about helmet use, focusing on the potential effects of helmet use on cyclist safety hardly seems like a negative portrayal. Again, red herring. I think you misunderstood someone. What Stephen was talking about, I believe, was helmet proponents' habit of harping on the supposed dangers of bicycling. That's quite separate from "focusing on the potential effects of helmet use!" -- -------------------------------------------------------------------------------------------------------- Frank Krygowski [To reply, remove rodent and vegetable dot com, replace with cc.ysu dot edu] |

They obviously don't, especially when you take into account that a cyclist with ten years of experience is one fifth as likely to crash as a beginner. Even at the LAB rate I would already have been injured six or seven times in my short career. For those crashes, median property damage was $100. That's roughly equivalent to a bent front wheel. Any crash that ruins a wheel is likely to cause injury. Median medical cost was $155, which would probably be less than a trip to an ER for road rash... snip OK, there you are. Eleven years at 2900 miles per year, roughly 32,000 miles, to rack up $100 in (say) a broken wheel, plus enough road rash for a scrubbing at the ER. Your implication that most adult cyclists who go to the ER are there for road rash is irresponsible. What kind of Attention Whore goes to the ER for road rash? I have a month's worth of the NEISS raw data right here (March 2002), over which I have been pouring with renewed interest. First of all, most people who go to the ER after a bike accident are children. I haven't seen the study you cited earlier, but I think it might be bunk because even among children, CT/AB (contusions and abrasions) are nowhere near the most frequent injuries seen at ERs. Among adults 20 yrs. old and older, the most popular diagnoses at the ER are LAC and FRACT. After that, I-O-I HEAD (internal organ injury, head), CT/AB, and ST/SP, then DISL, and a miscellaneous category with stuff like avulsions, non-head hematomas and amputations follow in about equal amounts. One must also assume that many of the adult CT/AB and LAC injuries are unusually serious in that category. A glance through the comments included with each case bears that out. Robert |

You can get your very own stack by contacting the USCPSC's National Injury Information Clearinghouse. Write me an email and I'll give you a phone number, if you want.

Your condescension is reaching new heights, which is really saying something. It is not my experience but your wacky theories that need to be revised. First of all, since my accident/injury rate and that of my "extreme" "adrenalin junky" friends is actually better by several orders of magnitude than the accident/injury rate identified by any study,new, old or imagined, of American or British club cyclists, it would seem that these club cyclists are in fact the ones who are not particularly cautious or skilled. RIGHT??! How do you explain the mediocre accident rate of CTC and LAB cyclists? My guess is it's due to their propensity toward daredevilism and pernicious lawlessness! For what else could possibly explain the difference? Like many "extreme" sports enthusiasts, What? you feel anyone who dedicates less time, or less willing to risk injury, isn't "real." Eh? You lost me. It's obvious to me that you are more willing to risk injury than I am. So for you, riding may be risky. Fine. If it makes you feel macho, do it. But don't pretend that your accident experiences are pertinent for someone who rides in a more rational way. Again, offensive. Dont pretend to understand the "rational way" someone who has already had a near-death experience navigates through traffic. These riders give new meaning to the word conservative. A profound caution that you can't begin to fathom is behind every one of their movements in traffic. Experience brings out new levels and nuances of caution in traffic that you apparently can't wrap your mind around. To you, everything is reeaaal simple. Teach a child to do it, right? But it aint real simple. Fact is, the rider who has competely eliminated his or her own mistakes will still be vulnerable to the mistakes of others. Fact is, your claim that simply riding lawfully will make collisions and injuries "vanishingly rare" is not supported by statistics, nor is it supported by the experiences of those who actually ride their bikes a lot. Personally, I think most people would call 3000 miles per year respectable mileage.

There are a lot of brand new cyclists on this forum who just caught the bug, and they are statistically five times as likely to wreck as an experienced cyclist. They should hear from those who have been there and back, not from those who haven't been there but who have crazy unsupported theories about what it's like.

Why do those guys suck so bad, Frank? Why? IOW, are you _sure_ you don't want to take up a different activity? Yeah, I rode 300 miles this week and hated every minute of it. I've got tomorrow off and I'm going on a long ride through the mountains. Boy, am I depressed. And scared!

I still refuse to believe that the helmet won't help in a spill, but wonder if the %chance of it helping offsets the % increase in likelihood of an accident due to lower awareness levels. Just how does a helmet lower your "awareness" level? Here's three possible ways: if something reduces one of your senses (hearing) or if additional sweat goes into your eyes and hampers your vision or if it irritates, and thus takes up some of your mental pathways so you have fewer paths to allocate to other mental processes (similar to one of the reasons cell phones reduce your dirivng ability) |

First Helmet : jury is out.
we live as immortals until faced with our mortality. some people don't
understand what mortality is until something makes it real for them. if your riding in a group you definitely need a helmet, cause you can never guess what the other guy is going to cut you off. if your getting sweat in your eyes then wear a sweat band under your helmet. I believe that the noise is less with a helmet as compared to no helmet. helmets can provide shade from the sun beating down on your head. I believe I heard it said that the aerodynamics of wearing a helmet reduces your overall ride time. I believe wearing a helmet reduces fatigue factor on the rider, which makes the ride more enjoyable. on and on - I didn't wear a helmet for the longest time either. I got used to wearing it and fell more confident wearing one. now I won't go riding without a helmet. I used to ride motorcycle, for 10 years. the times that I went riding without a helmet I regretted because of the comfort that my helmet provided me. now the details I won't bother you with, but 10 months ago my helmet saved my head. not only the fact that I did not die, but without a helmet I would most likely be missing part of the left side of my face - like my left ear or something - assuming I would have lived. and factor in the amount of money that it saved me. I spent 2500 dollars in doctor bills for emergency room, and I have no insurance. figure that without the helmet 50,000 dollars or more. now I am always thinking that something can happen - like a deer jumping out of the bushes or something. you know a deer when it sees you is either going to run or just sit there looking at you. I hit a dog once, it ran in front of me and then darted right back again and I hit it causing me to crash. so when speaking of AWARENESS LEVEL, can you predict what will happen. I was in the city on my mountain bike and waiting for a green light, truck on left blocking my left view, light turns green and I bolt on the green. car running red light stops 2 feet from running me over, and pedestrians as well in crosswalk on right of me. I say people should consider wearing a helmet when riding a bicycle. I have had: a fractured skull - woke up in hospital a concussion - woke up in ambulance broke my 4 font teeth - person gave me a ride home smashed up last year - broke collar bone, punctured lung, helmet saved my life - no health insurance ! person gave me a ride home.

Just bought a cycling helmet for my last short tour which encompassed quite a bit of city cycling. Never wore one before : don't think I will again. The added noise and irritation that the helment causes more than offsets the "possible" help it gives in case of a spill by deducting from my usual spacial awareness. I don't know. I still refuse to believe that the helmet won't help in a spill, but wonder if the %chance of it helping offsets the % increase in likelihood of an accident due to lower awareness levels. Just how does a helmet lower your "awareness" level? |
