Explain this then would you

OK. You're driving your car down the street at 45 miles per hour and a tree jumps out in front of you - hey, it happens - if you're NOT wearing a seat belt, you're toast (you might be toast even if you ARE wearing a seat belt). Almost everything in your car IS toast as it slams into you, the dash or anything that stops it from its headlong forward rush.

Almost everything that is.

Why don't you see flies smashed on the windshields of car wrecks in junk yards? Do flies not only fly fast, but also think fast enough to say to themselves in flyeeze, "Oh, shit, that tree's jumping in front of us, FLY BACKWARD, FLY BACKWARD!" WHAMMMMM! "Whew. That was a close one. Hey, what's everybody doing smooshed against the windshield?"

Go on. Go to the junk yard and look at the wrecked cars. And if the guy with "Bob" on his shirt asks you just what in the "heck yur doin'," I dare you to tell him. Oh please, please, please, please tell him. And then let me know what he does or says.

Do normal people think about things like this?
