Heavy

This is a sort of random question, but does anybody know what the word "heavy" means in the context of "He ain't heavy, he's my brother" or in the Beatles song "She's So Heavy"?

Burdensome. Or so I'm told.

Re: He ain't heavy..... Yes, Botley is correct insofar as it references something burdensome, troublesome, laden with issues.


Re: She's so heavy.... in that instance it refers to an individual that is introspective, thoughtful, deep, intellectual, philosophical.
