It blows my tiny wee Homo just-about-Sapiens mind that I have this brain which evolved to travel at walking pace for a few hours and think in terms of "you get loads of rabbits about an hour's walk from here behind those hills, and the really good berries are that way down towards the river".

And yet despite that it can quite happily plan out and navigate a route that is hundreds of miles long, at roughly 20 times the speed it was designed to travel at.

I'm sitting here writing a text message to someone 1800 miles away giving them directions to a shop in Vienna and I can visualise where they need to go for that to all work, with a brain that evolved to think about "not the next hill but the one after that" distance.
