go get your eyes checked - Divisions by zero

I can’t imagine having to live with my natural sight 24/7.

I definitely would not be driving. Probably not walking much either, might not see the bus coming.

Just a lot of dangerous animals. And dangerous humans. No cars though.
Imagine being in a jungle. Just a blur of greens.
It’s that a snake or grass? ¯_(ツ)_/¯
