It's not life which makes Varun Dhawan philosophical, but the science of slumber!

The actor feels it's true that the more you sleep, the more sleepy you feel.

"Good morning. Feeling so tired today I realised the more one sleeps the more sleepy he feels. Do you agree," Varun tweeted.

The son of popular director David Dhawan is busy shooting for his next "Dilwale", which also stars Shah Rukh Khan and Kajol.
