    If "My balaclava saved my life" sounds as rude to you as "you ain't got
    no brains," we're going to have to disagree on that judgement.

    Yep, I do. Because the tone creates rudeness as much as the specific
    words.

    I think both are inappropriate.

    Perhaps it's my background of academic training but I have been
    involved in many, many arguments over data and its best interpretation
    which have not devolved into name calling or snide remarks. Disageement
    often leads to more critical thining by both parties and sometimes to a
    better positoin which is different from any of the starting ones.

    There is no excuse to be rude. But I would point out that to some who
    are trying to have a serius discussion that comments such as "why not
    mandate walking helmets" can also be considered rude.

    May I ask why you feel such a comment to be rude?
    It seems to me that if I'm going to wear a helmet for some activities
    and not for others then I should have some rational criteria to decide
    when it would be most appropriate. Two that come to mind are the risk
    of head injury of each activity and the relative inconvenience of
    wearing a helmet while doing it.

    E.g. let's consider these activities: 1) bicycling on paved roads, 2)
    walking on sidewalks near roads, 3) walking up and down stairs, 4)
    driving/riding in cars and 5) motorcycling. Based on the statistics
    I've seen, the per hour risk of head injury is highest for the stair
    climbing, next highest for motorcycling, then walking, and lowest for
    road biking (although some figures show car riding to be pretty
    similar. OTOH, the inconvenience factor is by far the highest for
    stair climbing since it would require putting the helmet on and off so
    often. I'd put inconvenience at about even for walking and cycling,
    lower for motorcycling and lowest for car riding where there isn't any
    overheating issue nor any problem with storage/security when going into
    stores, etc.

    So based on those two critieria I'd be most likely to consider helmet
    wearing for motorcycling, next for walking on sidewalks, then for car
    driving/riding, and last for bicycling or stair climbing.

    It would also be nice to factor in the estimated effectiveness of
    helmet use in the various activities, but unfortunately the study data
    on this criterion varies widely (as seen in the numerous helmet
    discussions here). Motorcycle and car helmets can be constructed to
    absorb much more impact shock since they have fewer weight and heat
    considerations. But that may be negated by the higher impact speeds
    experienced in motorcycle accidents. OTOH, car accident head impacts
    are secondary impacts with the interior of the car and therefore of
    somewhat reduced magnitude. So my feeling is that car and pedestrian
    helmets may have the greatest effectiveness with bike and motorcycle
    helmets being less effective, but it would be good to have some better
    studies of effectiveness. Still not clear why bicycling should rise as
    high as number two among these five activities when deciding to use a
    helmet based on these three criteria.

    There is of course a fourth possible criterion to use, one which Frank
    has mentioned in the past. That one is the current fashion trend which
    indicates that one is likely to get odd stares and derisive comments
    when wearing a helmet for activities 2, 3, and 4 whereas one is likely
    to get some rude shouts (and tickets in some jursidictions) when
    participating in activities 1 and 5 without a helmet.

    and I know my balaclava saved my life." Perhaps that is not the intent
    but as the comments are ususally made so as to ridicule a pro helmet
    argument it certainly can reasonably be taken as such. Such comments
    appear in all the helemt threads.

    They aren't really rude, as much as they are witless and dense. The
    intent is to be both amusing and mildly derisive, though few people are
    amused or derided.

    Again, I don't disagree with the concept that you present. However, I
    do disagree with many of the statistics used to come to specific
    conclusions.

    But at a most fundamental logical level I also disagree with the
    argument that "two wrongs (or however many) make a right."
    So for me arguing that one should not do something - if that something
    is the right thing to do- becasue there is something else that one
    should do that they are not- just is not a good argument. "Don't
    bother to quite smoking because you are overweight anyhow" is not a
    compelling argument.

    Why is cycling and easy target as you suggest? At least part of that
    reason is that there are lots of folks that are convinced that helmets
    do some good, combined with the relative low cost and comfort of modern
    helmets.

    If indeed walking on the sidewalk is "more dangerous" than cycling then
    I believe there should be a serious debate on how to ameliorate that
    situation. That is different from concluding youshouldn't do anything
    about cycling safety unless and until you fix walking.

    True, but that fashion accpetance is driven by popular understanding of
    risk-wheter right or wrong. 30 years ago you would never fnd a pro
    hockey player wearing a helmet. But fashion and acceptance chaged with
    greater understanding of the the risk and a lower tolerance for simply
    accpeting whatever happened to them. I'm old enough to remember when no
    one wore batting helmets. Now ther are base running helmets. And no one
    makes fun of those that wear them. Do you think that would have been
    the case in 1955?

  5. gds said:

    I'll not argue about how effective helmets might be--but what you
    suggest will not help to understand that any better. Why? Because every
    trip to the ER that was avoided by the use of helemts is not part of
    the study.

    I find it difficult to believe that wearing a helmet would keep
    you out of the ER altogether even if it were effective enough
    to prevent a brain injury.

    If it saved you from having your head cracked open, I have to
    believe you still ended up in the ER with a broken collar bone.

    Count the ER visits of bicyclists with and without helmets. What
    percent of them suffered brain trauma?

    I know that I personally am a statistic for the dangers of not
    wearing a helmet when an old beater bike of mine lost its front
    fork just out of my driveway going about 5 mph.

    My unhelmeted head hit the stem bolt tearing the skin just above
    my right eye that required 15 stitches (and caused the loss of
    my ability to raise the right eyebrow for a couple months!).

    First question asked of me was "were you wearing a helmet?" My
    "no" response initiated a lecture on the dangers of not wearing
    a helmet, even though my injury was the result of an impact coming
    from *below* the level of where a properly worn helmet would be.
    A helmet would have made no difference whatsoever.

    Although I'm a statistic for a head injury while not wearing a
    helmet, I am NOT a statistic for suffering brain trauma while
    not wearing one.

    I don't find it hard to believe. But I really don't know the extent
    because I have not seen a proper prospective poulation based study that
    addressed the issue.

    Why? Broken collarbones are usually caused by "stiffarming" the ground
    sending the shock force up the rigid arm and thus breaking the
    collarbone. I've seen many broken collarbones happen without the head
    striking anything.

    Perhaps the lecture was an expression of the clinician's beliefs about
    helmet use which was unrelated to the specifics of your injury. Those
    are independent issues.

    Sorry, I am not going to collect statistics for you. If you don't
    want to wear a helmet, that's gonna be your problem and your

    I guess I'll just keep my mouth (mouse) shut about this from now

    I'm not surprised! Again, your reaction is EXACTLY the same as
    everyone else who has made your statements. When asked for real
    information, they evaporate ... except for one courageous psychologist,
    who admitted that yes, only 1% of his brain injury patients were
    cyclists, just as I said.

    Oh, the other bit of confirmation came from a woman in our bike club
    who was a full-time brain injury rehabilitation specialist. She, too,
    confirmed that in seven years of full time work, only one of her
    patients was injured while cycling. And since he was a racer, she
    assumed he had worn a helmet.

    It's not been a problem in all my 58 years. And since there are at
    least 1000 years of cycling per serious brain injury, I think the odds
    will be with me for several more lifetimes.

    it sounds like you have already had a head injury, Cars are not the
    only reason that people get hurt on bicycles, what about the many off
    road riders? I do not care if YOU wear a helmet or not but what I care
    about is that if you get hurt that you expect my tax money to pay Your
    doctor bills why should others pay for your right to not wear a helmet.
    Also why did you not answer Rob when he asked you about other ways to

    not able to prove your point.

    They know what to do, including wearing helmets --

    Why? Broken collarbones are usually caused by "stiffarming" the ground

    striking anything.

    Indeed, but attempting to break your fall happens whether you wear
    a helmet or not.

    A situation serious enough to crack your head seems likely to
    cause other injuries that would send you to the ER, so the population
    of persons that never see an ER because they were wearing a helmet
    is possibly a small one.

    Fact is, helmet or not, most bike injuries aren't going to involve
    head smashing to begin with, thus the belief by many, such as me,
    that the danger to my health of not wearing one is small. This is
    the way most people would feel about wearing one while walking or
    riding in their car. Not enough danger to be bothered.

    But you're not worried about your tax dollars going to pay for
    head injuries incurred while driving a car? Or walking? Or any
    number of other activities where a helmet might prevent a serious
    head injury, or one lessened by its use?

    Only head injuries incurred while biking?

    Would it be OK with you if someone didn't wear a helmet as long

    No need to stay in hibernation, Rob. And, I certainly hope you didn't
    feel I was picking on you in particular. This debate has been going on
    forever, and will forever continue. I just wish people would drop the

    Why can't we all just get along?

  16. OK Frank, clearly we view the world differently.

    You seem to feel very put upon by almost everything, have very strong
    views of the "worth" of the views of recreatinal cyclists vs.
    commuters, and feel that studies results are "bulletproof" in the face
    of methodological limitations and the existance of contrary findings.

    And of course you are very sure you are right.

    I believe you to be sincere in your beliefs and I also respect that you
    actually go out and try to do something about the issues about which
    you feel so strongly. However, I also believe that the combination of
    your prejudices and condescending attitude towards those that do not
    believe as firmly as you do will, I think, serve only to limit your
    effectiveness.

    Great thing about this country, you are free to proceed as you think

    I've studied this for probably ten years now. Due to my study of

    learned a lot. And yes, I think that as a result of that study (and
    changing my mind) I am now right. That seems to happen to most people
    who actually study this issue. They tend to become helmet skeptics.

    somehow mis-counting cyclists? Or do you think the people responding
    to telephone surveys were lying? (Actually, ISTM you need to claiming
    all _three_ of those things!)

    And here you go with changing the topic again. No where will you see me
    say anything about the MHL studies. The discussion is about helmet
    efficacy not compulsion. But you keep throwing up compulsion.

    What I have said that in the US there have periods of growth in cycling
    that have coincided with growth in helmet use. To be fair there are
    articles that argue both ways on this. But that is still very different
    from whatever the MHL studies found in Oceana.

    And of course you are very sure you are right.

    I've studied this for probably ten years now. Due to my study of
    literally reams of actual data, my viewpoint changed completely. I
    learned a lot. And yes, I think that as a result of that study (and
    changing my mind) I am now right. That seems to happen to most people
    who actually study this issue. They tend to become helmet skeptics.

    Of course that depends on yor meaning of "skeptic." I'm skeptical in
    the sense that I don't believe that the research gives a clear answer
    to the question of helmet efficacy. If that is what you mean I agree.

    But if you take "skeptic" to mean a belief that helmets are definitely
    worthless I think you will find yourself in the vast minority of folks
    looking at the studies.

    Of course we can't tell by counting the posters here or anywhere else.
    Clearly the self selection of posters is such that we are typical of
    everyone.

    I have always tried to avoid any ad hominum arguments, direct or
    implied. But you seem to find the need to resort to them. Says
    something about the strength of your underlying argument.

    OK Frank, clearly we view the world differently.

    Perhaps so. I tend to look on it as a learning opportunity.

    Again an attempt to argue by "putting down" the other person, in this
    case by implying I am not interested in learning. This does not
    strengthen your position and goes back to what I consider to be rude.

    You seem to feel very put upon by almost everything...

    ?? For a rather limited definition of "everything." ( I think you're
    looking at a small number of issues.)

    But include the issue under discussion as well as others that you bring
    up.

    Well, yes, for certain purposes. Not for others, it should be obvious.

    Not to me. It seems that you hae myriad snide comments about folks that
    wear lycra, or worse a helmet, and simply want to have fun. You imply a
    moral superiority to folks who use thier bikes to go to the grocery or
    library. That's How I read what you write.

    ... and feel that studies results are "bulletproof" in the face

    Once again, you avoid being specific!

    Assuming you're talking about the Robinson paper I cited and its proof
    of significant reductions in riding after MHLs: What _specific_
    methodological limitation do you see there?

    Do you think the trained observers doing the counts were somehow
    greatly in error? Or do you think the automatic counting machines were
    somehow mis-counting cyclists? Or do you think the people responding

    Gary, you're drowning here. Frank responded to your ad hominem arguments
    ("You seem to feel very put upon by almost everything", "And of course
    you are very sure you are right"😉 with statements about himself ("I tend
    to look on it as a learning activity"😉. You then call these ad hominem
    attacks on you, which did not occur to me until you mentioned it. At
    worst, its a case of "if the shoe fits, wear it".

    Cut it out. You have been providing heat but no light while Frank, who
    has done his homework, is citing literature. You are only looking worse
    with each fact-free attempt at rebuttal.

    !!! You're just going to throw that one out
    there and hope nobody notices??

    Well, you know how I feel about the data,
    er, estimates, but what I've seen shows
    that cyclists are injured at a much higher
    rate than pedestrians, i.e. 1000% higher
    per-mile.

    That study relies on estimates from the
    USDOT and WISQARS.
