Multitasking can be expensive, too—and dangerous. I learned that lesson a few years ago. I was writing a text message on my phone as I pulled up to a stoplight. Sadly, I misjudged the distance between my car and the one in front because I wasn’t fully paying attention. I hit the other car, though no one was hurt. Still, it was the most expensive text I’ve ever sent. And I learned my lesson.

I’m often asked if this is a generational phenomenon. Specifically, “everyone knows kids are better at multitasking.”  The problem? “Everyone” is wrong. Their brains, especially the limits imposed by short term memory, are the same as those of adults.
