I spent most of my military time up in the air or looking at aerial photos for camoflage (late 60's, early 70's). Conversely, I have a real challenge spotting animals when hunting. If they're not silloueted or moving, I have a real tough time spotting them.
Then there's my doctor who gives me my physicals. He asks me what I do at intersections, I say I do what everybody else does. He says, what if nobody else is there, I say then it doesn't matter.
