I remember as a child begging to stay up to watch Jack Paar and Johnny Carson and my mother finally giving in with the understanding that if I didn’t get out of bed on time in the morning or my school work suffered, the privilege would be yanked. I could stay up until 1 AM and still be bright and fresh in the morning. Now, the only reason I can keep my eyes open through Letterman’s monologue is that Alaska gets its TV from the West Coast which is an hour later than us. What shows up there at 11:30 PM, shows up here at 10:30 PM. Another faculty I’ve lost to age – the ability to be awake and coherent past 10:45 PM.
