Erm, that actually works. Some bird tried to eat my arm one night, thinking it was made of chocolate.
A perfect example of confirmation bias

Your decision is that Lynx worked, the alternate hypothesis that it is simply a different deodorant from the night before, and could have been any has not been considered


As I said a classic analogy for the "helmet saved my life"

You believe Lynx worked, and are simply choosing to support your own belief


This is the way that the poorly worded and extravagant claims work... People want to believe that a helmet gives "complete protection" and when they see it in the advertising puff choose to believe the lies as it confirms what they believe

This thread was on my mind when I was in All Terrain Cycles in Saltaire idly browsing my lunchtime away. I looked at helmets for the first and a last time in my life, the first one I picked up was £129.99, the second a Giro Aeon (or summat) about £180. Wowee! I had no idea, I though they were about £20 tops. :ohmy:

Yet, for some reason, almost all the advertising seems to be pro-helmet. The £5 and £10 buffs, beanie and cap makers just aren't advertising as much. I can't imagine why, can you? :laugh:

I'm joking, FFS.

As the marketeers would have it, reassuringly expensive.

The more you pay, the more air you get for your money as there are more vents. No evidence to suggest more protection though.

And of course, if you drop it you need to buy a new one. And if you don't drop it for 3 years you need to buy a new one
 
So, I haven't read this whole thread (please tell me no one has!!) but I wanted to vent about something I found on the web. It's the form for getting a medical exemption to compulsory helmet laws in Victoria, Australia (ie Melbourne and surrounds). https://www.vicroads.vic.gov.au/~/m...pproved_bicycle_helmet_in_victoria.ashx?la=en

Don't bother downloading it, here's the bit that makes me furious.

This medical report will be forwarded by VicRoads to the Victorian Institute of Forensic Medicine (at VicRoads’ expense) for an independent opinion. You may be contacted for further medical information. Please note that exemptions are only granted where a person experiences extreme difficulty [my bold] in wearing a bicycle helmet.

There is no requirement in Australia to get a doctor's letter if you want to sit on your increasingly fat arse all day, even though that is much more dangerous than cycling without a helmet (I assume in pro-compulsion lobby are aware of the relative dangers of inactivity).

I wonder what "extreme difficulty" is? Blinding migraines? Arterial bleeding? Coma?

It's fair to assume that if you get dermatitis where the strap touches your skin, that wouldn't be described as extreme, but who's going to cycle if it means you have a constant rash on your neck. A headache that develops after an hour of wear? That's not extreme, but again, who's going to risk a headache for a ride.

The religious exemptions are much less onerous. I briefly thought the solution would be to become a pastafarian, but I think wearing a colander on your head to avoid wearing a helmet might be taking things a little to far. :smile:

Thank you. You can resume your discussion now.

In fact the reality is the opposite.
Helmets need absorbent material to absorb the energy of an impact.

As a helmet gains more holes the amount of absorbent material decreases and the ability to absorb energy decreases

Then there is a structural problem as the remaining material needs to be denser ( and again less able to absorb energy) to support the shape

As a bonus you can then add a carbon fibre cage and a small layer of dense material to provide a helmet that is cosmetic, but has very little material to absorb energy and a hard cage

Modern helmets are far less efficient than those of 20 or even 10 years ago

But why worry about the ability to actually absorb energy and reduce the effect of an impact when you can fool people with blurb:
Unsurpassed ventilation is achieved by means of 26 large air vents, a design feature made possible by the reinforced helmet frame - all delivered without any compromise to the safety or aerodynamic qualities of the helmet

Make the fact that you have compromised the helmet's efficiency a selling point and the fools will believe ypu

You pay more for less then? That's why I don't buy Aero chocolate bars, you can't fool me...............
At the right temperature I could suggest that strapping Aero chocolate to your head is as effective in a crash as say a Kask helmet. I haven't got any evidence though. Hey maybe it's time to visit the marketing people

And I bet you got a shock when you went in the pub and found that beer wasn't 50p a pint any more!!!
