Math and Sleep

Some days back, I had to answer a simple mental math question. But it wasn’t easy for me, though I knew how to solve it. It took more than the standard time required. I became sad about it and thought – what is wrong with me? Why is my brain dull today?   

After analyzing how my days were in the past couple of days, I zeroed in to one thing – lack of sleep. I observed how well I am with math whenever I had sleepless nights.  I found out that many a times it even takes more time to understand a question, hard to recollect the formulas and methods...

Then I decided to write down the names of all the people I know who are good at math and check how well they sleep daily. I had to wait for couple of days to get replies form some people.  I knew 15 people who are really good at math and surprisingly, ALL of them sleep very well.  Among those 15, there is one particular guy who is kind of math lover. He still keeps his math text books with him and solves problems when he is bored or after a ‘fight’ with his wife. When I asked his wife how her husband sleeps, her answer was:

“He sleeps like a baby”

Should I tell more?
