It's hard to believe that as smart as they are, they can't host an entertaining lecture. So, they make their talks a little less interesting than they could be for the benefit of us. That way we can squeeze in a quickie. As long as we're not burdened by the curse of snoring, it's relatively easy to nod off in class. They truly care for us and support our napping adventures.
Naps support the economy.
All sorts of products are on the market to support taking naps. Japanese companies will come set up tents at your company to give employees a space for a quiet nap. Tow-truck drivers make a decent living hauling away people who napped behind the wheel. Hit the snooze. Then you can take a quick nap before it wakes you up again.
