I can imagine some people can't sleep because of job related stress.<quoted text> Aside from the fact that an increasing number of Americans who don't take cocaine also have sleeping disorders, MJ had trouble sleeping back when he was in the Encino home.
They go to work everyday and are overburdened with the work load.
MJ did not have to go to the office every day.
He was a pop star that did not perform in 12 years.
Why would he have trouble sleeping?
The answer is obvious.
Drug abuse that got worse over a long period time.
