"Mama," my nine-year-old son said. "Did you know that stress can kill you?"
"Yes," I said. "Everybody knows that."
"Did you know that sleeping can kill you, too?"
"Um, no. How so?" I asked.
"If you sleep a long time, your arteries will clog up. Then blood won't be able to get to your brain or heart. And then you'll have a heart attack or stroke. Which will make you die."
"Oh," I said. "But if I don't sleep then that will be a stress on my body, which will produce the hormone, cortisol, which will give me a heart attack or brain aneurism, which will make me die."
My son thought about that. "Yeah."
"So I'm going to die either way," I said.
I think I'll sleep. It's the better way to go!
