helmet, again

I have not found any data to support the claim
that helmets are good.

Data suggests that blows don't have to be that
hard for the helmet to be of little use.

Also, the helmet makes the head hit area much
bigger. By wearing an arborist helmet in the
forest, countless of times I have been
surprised by hitting my head whereas normally
I wouldn't. This tells me that the proportions
of the head is extreamly ingrained and it is
very conceivable in an accident situation where
survival mode kicks in, to be able to tilt or
roll your head away from danger, something
that'll be more difficult (because of the
size), and worse much less intuitive with
a helmet (because of the head "size change").

I'm not a helmet zealot, but your argument fails
because the human head weighs about 5 kg. Instinct
in protecting it is over-ridden by the strength required
to controling head movement when it is subjected to the
high forces of momentum.

Disregarding the danger, yes wearing a helmet at work usually results
in "bumping your head" more since as you say, the "head is now 3
inches or so larger.

I was at one Air Base that apparently the Commander liked helmets as
all maintenance men had to wear them. A giant pain. You'd been fixing
generators on those engines for ten years or more and all of a sudden
you couldn't get your head inside the nacelle to see what you were
doing :-)

You need to work on your research skills.

Hey! We did.

Guy tells us that it takes a fully equipped machine shop to make a
home in a piece of aluminum tube. My 12 year old grand daughter proved
that wrong, she was able to accomplish this highly difficult task.

Then the guy tells us that bright flashing lights protect you. Even
alleged that with flashing light cars would run and hide. Nope, had my
wife test this. Walked around with a real bright flashing light. Some
of the neighbors looked at her sort of funny but not a car seemed to
notice her.

Then there was the car top bike racks. Nope, not needed. Bangkok is
the second most congested city in the whole world and yesterday I went
out and rode for about 90 minutes. No rack, nothing but me. And I'm
going out tomorrow too.

So our research shows that you are batting 0 for 3 and in baseball
terminology, "three strikes and you are out".

In theory, yes.
Sometimes there is a 70kg bag of meat x velocity smashing
the 5kg thing into the pavement.

UK's leading scientific journal even suggests that wearing them causes a
bizarre mental state identified as Jute syndrome:
