Was Michael Jackson working out six hours a day, emaciated, and dehydrated at the time of his demise?

I would find it really sad if Michael Jackson succumbed because he just worked out too hard in preparation for his upcoming world wide tour. I heard that Michael Jackson was just too skinny and dehydrated for his body to hold up to the intense six hour workouts he may have been doing for his upcoming tour.

When the news channels started showing clips of Michael Jackson performances from the 80's and early 90's, was he possibly trying to do all of those routines and probably new ones as well for his upcoming tour? If this turns out to be the case, it might be an amazing gesture if all the people who pre-purchased tickets for his upcoming tour allow the money to go towards Mr. Jackson's debt and some other worthwhile causes as well. Michael Jackson may have died for his art.
