I have seen pics on other mine forums and UE sites where there have been a mix of non helmet users and in the same group people with helmets on, including kids with no head protection - my mind boggles at this.
I have to say Mike, you will often (the majority of the time in fact) find me
not wearing a helmet.
Initially this was because of what might be called ignorance. However, since then it evolved into a conscious decision. My thougts and reasoning are as folows. I do not do SRT nor some of the more "extreme" explorations. I have found from experience I knock my head on things far far more when wearing a helmet than when not, in fact I can only remember knocking my head once when not wearing a helmet. Taking this one step further, in knocking my head
with a helmet on I am far more likely to cause myself problems than otherwise i.e. disturbing loose roof material timbers etc. The places I go (mainly slate mines) if any rock was to land on my head a helmet would make little or no difference, I would still be dead!
There are of course exceptions to the above. For instance the working parties at Cwmorthin where a "working activity" is going on, and a few mines I consider a helmet more desirable. One more thing if I do wear a helmet it always has a chin strap.
I might add, the first time I was shown round a working mine (over 30 years ago) I didn't have a helmet on, nor did the mine manager who was showing me round!
