Laughter essential for Big B

With rising stress levels in today's day and age, laughter seems to be the only way to combat it, feels megastar Amitabh Bachchan.

The 71-year-old took to his blog to talk about the importance of laughter and how it often "liberates" people.

"Laughter is indeed the food of love...of the removal of stress and the expression of one that may have been oppressed, now liberated," Bachchan posted on srbachchan.tumblr.com Thursday night.

The actor is busy shooting for his film "Bhoothnath Returns" and other endorsements.
