I want to cry. This is what our school systems produce. I knew it, but it's much more heartbreaking to see.
Malcom, do you know what psi stands for?
Can you tell me the psi of a standard garden hose?
How about the psi of a pressure-washer?
Can you see no appreciable difference?
I just watched a show on Discovery Health about a man who was suffering embolisms, and the docs couldn't figure out why. A couple of years before, he had been pressure-washing his deck when he hit a wasp's nest on the underside of the deck, through the gaps in the boards.
When the wasps swarmed his legs, he wasn't thinking, and turned the hose on his legs to wash them off.
He washed off a lot of his own skin. And he damaged the blood vessels in his legs so badly, they began to form embolisms (blood clots) that almost killed him years later.
Now, you go outside, turn your garden hose on full-blast, and try to wash off your own skin. I am not advocating you hurt yourself, because I know you won't be able to do yourself any harm in that way.
I'm going to go sob over the state of our schools.
