It is supposedly recommended by doctors that a very small nap in the anoon helps one to gain energy and calm nerves much more than anything else ! :)
I saw a program on TV recently this weekend which showed the ingenuity of an Indian born American in trying to "help" people sleep during office hours, taking a cue from the above advice ;-)
The Empire State Building in New York is one of the largest buildings in the world and houses a lot of corporates. The said business has set up a sleeping center which allows paying members to come there and take a nap in specially designed sleeping couches, for about 20 mins, amidst absolute tranquility.
Corporates are sending their top execs by the dozen so that these people can get energized very quickly (after the catnap) and get back to work rejuvenated.
How interesting ! Now, if only ... :)
