About celebrities, most of them are ignorant to the fact that they have lost touch with reality. Being fawned over and drown in excess is not reality. It is no wonder they are insane. It is the have-nots who glorify their excess and I simply love to learn about famous people who are actually decent...or so their narrative goes.

I think another factor is that for many of them to be the "entertainer" type, their personality is predisposed to being more addictive, more depressive, and more excessive.
