Five pages of heartbreak.

This ranks as a top sad-making story: a five-page piece about overworked and frazzled parents who accidentally leave their kids to die of hyperthermia. First reaction is, "Oh, those dumb people didn't deserve kids."

Then you get the brain experts, telling us how times of stress can overwhelm even the most prepared and conscientious minds. You get the molecular physiologist saying:

"Memory is a machine," he says, "and it is not flawless. Our conscious mind prioritizes things by importance, but on a cellular level, our memory does not. If you're capable of forgetting your cellphone, you are potentially capable of forgetting your child."

And you get a quote like this:

Then there is the Chattanooga, Tenn., business executive who must live with this: His motion-detector car alarm went off, three separate times, out there in the broiling sun. But when he looked out, he couldn't see anyone tampering with the car. So he remotely deactivated the alarm and went calmly back to work.

Jesus.

Don't read this at work.
