Einhorn's Secret Weapon: Napping

David Einhorn is a very clever chap: the game room in his offices includes a vital piece of furniture.

There is a game room with a pool table and a bar, but it doesn't look like it's seen many wild parties lately. The room also contains a couch on which Einhorn often takes an afternoon nap--he's very serious about his naps.

Turns out, napping is a truly wonderful thing, and all of us should do it. According to the Boston Globe:

• Research on pilots shows that a 26-minute nap can enhance performance by 34% and alertness by 54%.
• A 20-minute nap enhances alertness and concentration, elevates mood, and sharpens motor skills.
• A 45-minute nap can include REM sleep, which enhances creative thinking.
• A nap of just a few minutes is effective in triggering active memory processes.
• Just knowing a nap is coming is enough to lower blood pressure.

Given all the advantages of napping, why is it, do you suppose, that it's so vanishingly rare in the business world? This is one of the great aspects of working from home: you can take a quick nap pretty much whenever you like. I highly recommend it.
