"It's better to admit stuff is random and leave it at that "

I dont agree with that line.
I agree that we take input from our surroundings, some of which is unconciously or subconciously. We react to this, but when we try to find out why we are reacting we learn more and become more in tune with our environment. Then when it counts we might react sooner to danger.

An example with myself when I misread danger signs is when I was walking down a track in bush land a while back and I beleive I have reasonable experience with my local bush land. A bird was quite vocal reacting to a threat. We have a small bird here (Australia) called a Willie Wag Tail and it has a distinctive sound when there is a threat present. I initially thought I was the threat, and took my focus off the track, and watched the bird as I approached. Something seemed wrong, and my hackles went up and stopped. It wasn't reacting to me as the threat, it was reacting to a 3 foot long Tiger Snake which was 5 feet in front of where I stopped. (TigerSnake being the 3rd most deadly snake in Australia)
The snake looked like some bark shead from the local trees, and unless you look for them you dont see them, and they hold there ground and dont rush and hide like other snakes.
If I had not had the experiece of seeing what the birds reactions are like then, and more importantly subconciously learning what they are like, the 'little voices' wouldnt have deafened me into stopping 2 steps from being bitten.

We react to sight, smells, sounds, weather, etc subconciously everyday, and I believe my little voice needs the exercise. I think we are to complex to understand, and if we do one day understand our complexity, we will disappear in a puff of logic. <img src="/images/graemlins/smile.gif" alt="" />
Until then, tune in and enjoy the show our little voices have to offer and who knows we might even learn something new.
