Resolutely on topic
Maybe they are embarrassed to come out and say they had an accident without a helmet and it hurt their head a fair bit!
After all they could have reduced the "hurt" by errrrrr wearing a helmet :okay:
I've had two offs in the last five years where my head has made contact with the ground. The first time, wearing a helmet, I misjudged a fast descent on a loose surface and badly scraped face, shoulder and hip along the gravel. The helmet was unmarked and did nothing to reduce the hurt but It was this event that prompted me to look at the value or otherwise of helmets. The evidence is that, averaged across the population, they are unhelpful.

The second time was on the commute, a car emerged from a side road without looking. This time the damage was a bruised cheek bone, a sore wrist, two bent wheels and a pair of glasses. My woolly hat survived to be worn again.

I'm not embarrassed about either incident, despite both hurting my head.

Well, it seems that helmet users are much more frequently head-banging, so it was ever likely to happen at some point.
I have seen very few reports of "head banging" certainly not enough to form any opinion.
Helmets really are fantastic self-advertising products. It seems they destroy themselves very photogenically in minor crashes, giving their buyers a real "you made the right decision" positive feedback so they rush out and waste another £10 to £350 and it's very difficult to dissuade them of that, to point out that the likely alternative was not to suffer a head injury and possibly even no crash at all.
The statement that "the likely alternative was not to suffer a head injury and possibly even no crash at all" completely disregards the fact that accidents happen and nasty head injuries happen, and even to non helmet wearers.
Can we think of other products that con their users into buying them again and again because of how smart they make them feel...?
Please provide evidence of anyone who wears a helmet because it makes them feel smart.

Except it wouldn't have been the same force - it would be about half a pound of helmet lighter, which may even be enough of a reduction that your neck may have been able to keep your head from the ground, doing a job that necks have evolved to do.
I agree it wouldn't have been the same force although as it was me that experienced the amount of force I would not have wanted to experience even half the force on my unprotected head, I also appreciate that a non helmeted head is smaller so would have had to travel perhaps a whole 25-40mm further before impact, so while I completely agree that the neck may have been able to keep my head from the ground, however equally it may not have been, after all an adult human head weighs about 11lb or so, the extra half pound or so of helmet will have only a very small effect on the amount of force exerted. Of course that extra 25-40mm of travel may or may not also lead to a neck injury.
Also, the edge of most helmets is not part of the tested area in any of the current standards. It seems highly unlikely that the manufacturer designed that bit for anything more than looks because making such an area protective would be unnecessary cost which would leave them open to allegations of dereliction of fiduciary duty from their shareholders.
None of which has any bearing whatsoever on anything really, you appear to be suggesting that the side of the helmet will not provide any protection. The evidence of my incident and the damage to the side of the helmet and lack of damage to my head provides reasonable evidence, in my humble opinion, to the contrary.

Given the government's statements that the low rate of helmet use is a strong reason they haven't introduced compulsion, it's not possible to be "very much pro-choice" and use a helmet. If you use a helmet, you may be theoretically pro-choice, but your actions are taken as support for compulsion.
I'm sorry this is nonsense, who are you to tell me I may only be theoretically pro choice and that it's not possible to be very much pro choice? I choose to mostly wear a helmet when cycling, occasionally when out with the wife "pootling" along the canal tow path or leisurely winding our way along some of the local greenways I will choose not to wear a helmet, if out on the road bike on a training ride I will always choose to wear a helmet. I will always support your choice to wear a helmet or not too, there is nothing theoretical about it, the very definition of "very much pro-choice" I would say. If some other person or even you decide that me mostly wearing a helmet is somehow support for compulsion they are wrong, very wrong.

I caught myself doing it too. When I used helmets, I crashed more. I think the last time I used a helmet, I crashed... and I realised it was because I'd used the dratted thing instead of actually attempting to address the reasonably-forseeable cause of a crash. Fortunately, the bike only suffered minor damage.
I am pleased that you and the bike didn't suffer major damage. Yes some crash causes are foreseeable, not all are though, just as some crashes are preventable and some are not.
Since stopping using a helmet, I don't think I've ended up on the floor yet. The bike has done once, but I'd jumped off early :laugh:
I hope I don't have to read that you have ended up on the floor, and fervently hope not to read that you, or anyone else for that matter has sustained injury.

It's absurd, though. You use a helmet in case of an unknown event while cycling but don't use one in case of an about-as-unlikely unknown event while walking - one of those decisions must be wrong and I don't think it's the walking one...
Actually no neither decision is wrong, the reason being I do not accept the premise that the likelihood of the unknown event while walking is the same as when cycling, it is lower and low enough for me to consider that wearing a helmet is not required while on foot. I can't recall falling of my feet and banging my head since I was a little kid many years ago, fell of my bike and banged my head on Monday and I have done many times more miles on foot than cycling.

They don't often say it, but as in my experience, I used a helmet instead of taking sufficient care and crashed as a result. So I think risk compensation is a reality and not absurd at all.
I did not suggest that risk compensation is absurd, I have no doubt at all that risk compensation is a reality, it does not however account for all accidents while wearing a helmet, and suggesting that all accidents while wearing a helmet could be prevented by not wearing a helmet and taking more care is the height of absurdity. As would be the concept of wearing a helmet so the rider does not have to take any care when cycling.

It's actually all very simple.

I would much prefer not to have an accident and I take reasonable care to try and prevent them, I am of course still human and will make mistakes, as will others and they may still happen. In the event of an accident that may lead to some form of head impact I would prefer to have some level of protection on my head. Now you can argue all you like whether cycle helmets provide sufficient protection or not, it seems reasonably clear to me that there isn't sufficient hard data on this so we are left with making a decision based on some scientific evidience, anecdotal evidence and our own personal experience. As long as we are all permitted to make that decision for ourselves and not be castigated for that decision I am happy.

I agree, as perhaps post 4 (requoted a few posts back) illustrates - even if I (and others) tend to diminish the importance of anecdotal evidence because it needs so much doing to it to make sense of it.

I tend, naively, to assume that the population at large (as represented by posters in this thread) have got their minds to the home run that says that good quality statistical evidence is the gold standard for assessing population-level risk data and applying it to individual choices. In fact, as the last few pages illustrate, the population hasn't even worked out how to pick up its bat, let alone where the batting plate is.

Which is very sad indeed.
Hey, steady with the sporting analogies, I'm the one in America at the moment :smile:!

The difference of emphasis is that my professional background makes me suspicious of all data - the supposedly gold-standard epidemiology, even the ultimate randomised controlled trial included - "because it needs so much doing to it to make sense of it."

I think there is a danger manifested sometimes on this thread that in our desire to stop people drawing superficial and erroneous conclusions from "case reports" we downplay the genuine learning to be had.

In fairness I think you may have missed mine when I said my cloth cap made me feel indestructable :smile:
Oh sorry as you appear to be so anti-helmet I took that as fact that you thought it would protect you as well as a helmet would, which could actually be true & logically in this instance is.

You've not yet been here two months, so either go digging with the search among the old helmet subforum threads if they're still accessible or simply stick around...

The statement that "the likely alternative was not to suffer a head injury and possibly even no crash at all" is astounding and completely disregards the fact that accidents happen and nasty head injuries happen, and even to non helmet wearers.
No shock, but accidents are very improbable and nasty head injuries an even more improbable subset of those - hence the comment. Many helmet users seem to lose all sense of proportion and act as if crashes are an inevitable part of cycling, which may explain why they seem to report having more of them.

Please provide evidence of anyone who wears a helmet because it makes them feel smart.
Why? Is the search function broken for you? A quick smattering from this thread and I'm sure there's many more, both on this forum and others:
But I don't need evidence if it's something I believe and makes me feel better and more confident,

When I used to wear a helmet quite a few years back - I was an early adopter - I certainly felt more confident, and

I just feel happier with it on.

I'm sorry this is also mostly arrogant nonsense, who are you to tell me I may only be theoretically pro choice and that it's not possible to be very much pro choice?
Not what I wrote: I said that you can be as pro choice as you want in theory, but your helmet use is interpreted by government as support for compulsion.

you appear to be suggesting that the side of the helmet will not provide any protection.
Sorry about that because what I'm trying to suggest is that one can't count on the side of a helmet being protective because it's outside the standard test areas. Unless you know better and can point to a statement from its maker that the helmet provides protection over a larger area?

The evidence of my incident and the damage to the side of the helmet and lack of damage to my head provides reasonable evidence, in my humble opinion, to the contrary.
And yet, we've had a materials scientist attempting to explain why the damage is indicative of a probable failure to protect. This is a great example of what I mean by helmets being a self-demonstrating self-reaffirming self-advertising product.

If some other person or even you decide that me mostly wearing a helmet is somehow support for compulsion they are wrong, very wrong.
Great: so the government's wrong. Wouldn't be the first time. That still doesn't change the reality that your helmet use is interpreted as support for compulsion.

I do not accept the premise that the likelihood of the unknown event while walking is the same as when cycling, it is lower and low enough for me to consider that wearing a helmet is not required while on foot.
OK, how do you explain why many estimates (example) suggest that walking has a higher injury rate than cycling then?

I can't recall falling of my feet and banging my head since I was a little kid many years ago, fell of my bike and banged my head on Monday and I have done many times more miles on foot than cycling.
Yet the last time I fell off my bike and banged my head was around thirty years ago, whereas I fell off my feet and banged my head in the bad winter of 2010/11. I'd be interested to know how many of your bike head-banging falls were when you wore a helmet and how many were the rides where you didn't, if you know such things.

I would much prefer not to have an accident and I take reasonable care to try and prevent them, I am of course still human and will make mistakes, as will others and they may still happen. In the event of an accident that may lead to some form of head impact I would prefer to have some level of protection on my head.
That seems like a demonstration of the unreasonable acceptance of a head-banging crash as a necessary part of cycling which I described above. We probably disagree about what "reasonable care" is. I would say "on your own head be it" and leave you to it, but the sad reality is that your helmet use moves the UK a step closer to everyone being forced to wear them and the consequential reductions in cycling and increases in injury.

Is there evidence of this? you seem to be of that belief so much so you mentioned it twice.

I have, and I know others here have too, been variously castigated, abused and cajoled for chosing not to wear a helmet, I've actually been threatened with physical violence for not wearing one. I do find that it is invariably the case that if an individual is prepared to have a chat about my decision they rarely if ever have even the most basic knowledge as to the limitations of cycle helmets and I think that your suggestion upthread of some sort of rating system or at least some more transparency from manufacturers would be worthwhile. Too often in conversation I get the impression that some cyclists believe that the helmet is tantamount to a suit of armour, either that or they think it makes them look pro.

Parts of this thread have descended into bickering again.
It is being temporarily locked for 'cleaning up'.

A number of posts have been deleted, for varying reasons. Some were off topic, some had descended to personalities, a few had nothing wrong in themselves but were part of a deleted sequence and would have made no sense if left.

Please try to stick to the topic, keep personalities out of it. And remind yourselves of the rules in post 1.

Somebody far cleverer than me can I'm sure give us some indication as to the speed Andys head would have been travelling at the time of impact
Let's simplify Andy's head to a bowling ball moving in a vacuum at 12mph, 2 metres above the ground. If you dropped an object from 2m, it would hit the ground at 6.3 m/s (sqrt of 2ad) or about 22 kph/14mph. Adding the two perpendicular vectors using Pythagoras, his bowling ball head would have hit the ground around 18mph.

HTH
 
Why would yu want to do that & what relevance to a falling hammer is a speeding car, please at least keep it on topic
..... and there was me thinking that the cyclist would have been more likely to meet a speeding car than a hammer

Just goes to show how cycling conditions differ across the country

Re-introducing the hypothetical pedestrian and introducing a second hypothetical dropped hammer. Both get hit on the head, both get taken, in the same ambulance to the same A&. Who gets lectured on the virtues of helmet wearing?
Motorcycle paramedic he says hopefully......

As a compromise I've ordered one of these. The colour matches the bike, after all one has to be fashion conscious.:dance:

will get the wife to sew them together & see how things work out. Already ordered a high vis' jacket, unfortunately I didn't notice the elbow & knee pads I'd ordered were from China so won't arrive for a couple of weeks.:reading:

Trialled my new haute coiture home made job today. Results, peak too long blocks forward view, sweaty in hot weather, made pedestrians get out of the way :gun::gun::gun: Maybe a winter hat???

Why has no one responded to this? If anyone cares about safety, I'd have expected somene to comment on this.

What are you thinking, @stearman65? That cap is build to EN 812, it's not built even to the minimal standards of a bicycle helmet. And if you google the standard, it's tested with
a 5 kg flat striker is dropped onto the helmet from a height of 250 mm
and a penetration test
500 g striker dropped from 500 mm)
which is so far below the forces in even a low speed crash that your hat would be of no more protection than a baseball cap. Even in a trip, the distance fallen would be nearly four times that, and the weight would be your body weight, so 20 times? That indicates that if you were in a collision, the forces involved would be nearly 2 orders of magnitude (80 times) greater than the hat was designed to withstand. At that level of force, it might fail catastrophically, and shatter, pushing sharp plastic shards into your scalp.

And that's if it's actually meets the standard it's claiming. I would not buy safety equipment from an eBay seller unless I was really sure that it was built as described.

Please don't wear this anymore.

However in the history of this forum every single piece of first hand evidence from people who have actually fallen onto their heads whilst wearing a lid has been dismissed out of hand..
This isn't true, the most recent example is that I have told Andy that I believe his helmet may have helped in the circumstances he described.
