Ever thought ?
How entertainment is a source of energy ? How I cant prove mathematically here– May be someday when I get time– I can try !

And do ask the entertainer—- has she/he depleted of energy that you just got abundant of—–
As per Physics-“energy is neither created nor destroyed, it can be changed from one form to another” — So it was in you–
Do check your weight after the BIG LAUGH THEN!
