A half a lifetime ago, I stayed up until midnight. If you were 16 with a permit, you could drive with any licensed driver. So at midnight, I got in my mom's shiny red firebird, T-tops off, and we drove all over the place until the sun came up. I snuck a nap in, then headed to the driver's license office where I got my license on an hour of sleep.

Double that, and for my birthday this year, my son slept through the night. It was just as good.
