Snow Blindness is a condition that happens as a result of seeing nothing but white snow for long stretches of time that literally results in blindness. Not gonna happen here in New York, but in huge open stretches of land with nothing but snow, it does.
Sure, seeing nothing but the person you're thinking about all the time can make you blind, but is it really such a bad thing if it keeps you warm and protected.
"We don't value the lily less for not being made of flint and built to last. Life's bounty is in it's flow, later is too late. Where is the song when it's been sung, the dance when it's been danced? It's only we humans who want to own the future too."
- Tom Stoppard, Shipwreck
