I've been told several times by reasonable and also a couple of very smart people that I'm the most curious person they've ever met.
I realise that I have an extreme curiosity level - I don't know where it comes from.
There's a continual stream of thought - out walking or gazing out the window - the little voice says - look at that! or what's that? - how it that?
etc etc.
I find deep curiosity in the world where others don't notice things -yet, I have zero interest in many things that others basically live for ------- mysterious to me.
