here we go again

I has been established scientifically that subjective time is variable and for good reason.

A clock when first looked at ticks slowly over the first tick and then looks to be "normal". Because we register a scene as it changes but once it's syntax is "clocked" we predict most of the vista &/or movement and get on and look-out for attackers - or whatever. Evolution gave us a reason to vary time - in our heads.
