Hammocks kill small children

My childhood summers were consumed in imagination.  The yard from my parent's old home is the best kind for dreaming.  It was gigantic!
The back yard was big enough to house a fully functional garden with snap peas, grapes, strawberries, raspberries and a giant apple tree, where my dad fashioned a treehouse of sorts--but it was more like a couple of wooden slats nailed together.
The front yard was where my imaginations came alive.  There four or five trees in the yard, a couple of them were perfect for climbing and perching with dreams of conquering dragons or taking flight.  I dreamed a lot in the front yard, books in hand or friends in tow.
Two of these trees were even close enough for a decent hammock. In the summer the rope deathtrap sat between the two trees, unused for the most part.
I noticed that lovely rope swing as a perfect place to read and daydream. The weaving was more stable than a rocking branch and it cuddled me like a bed in the shade of the trees.  Perfect for a hot summer activity when my brothers and I were too loud for my mom's sanity.
During one of my reading adventures, one of my brothers came over to annoy me. He started pushing the hammock while asking me questions about what I was doing...what I was reading...and just being annoying.
Out of the blue he asks, "Hey, Michelle, can I do an underdoggie with the hammock."
"No. I'll fall out." Not to mention, Derrick is a good eight years older and contained more strength in one of his gangly limbs than my entire nine-year-old body.
Almost immediately, he began to back up for a run, "I'm gonna do it anyway."
I didn't even try to get out of the hammock. (Try to do jump out of that rope booby trap fast and the damage could be worse).  I braced myself and hoped the ropes would just wrap around me as a cage. They didn't.
The hammock flipped upside down and I fell face forward--my forehead smacking a one of the roots.
My nine year old logic was solid, but my brother's curiosity and ignorance caused this hammock to nearly kill me.
There's been a lot of talk about injuries from trampolines or playgrounds. Screw those things, stay away from hammocks or older brothers.
