Why is it (my totally unfounded and un-researched belief) that people who are born missing limbs do not generally receive/obtain prostheses, yet those who are mangled during the course of their life often do (resources permitting)?

And is this living proof of the adage, “ignorance is bliss”?

And, more importantly, do those who grow up with limbs develop neural pathways that then feel neglected when a limb is lost, whereas those born with imperfections develop different pathways altogether and never have need to feel disabled or inconvenienced by their situation?

Hmm.

Why is it that Brits direct both auto and foot traffic to the left side of the road, and yet when you’re standing on an escalator, they have the same rules as we do for standing on the right and passing on the left? Shouldn’t the slow lane rules be switched as well?
