All the stuff that was injected in him to lighten his skin color and other things (drugs) probably wasn't long term very healthy for any human being, so some of that stuff may have had something to do with a short lived life.
He was the Elvis Presley of the 80's and early 90's why the man wanted to fuck his body up he only knows, he was so BIG he could have had more pussy than Hugh Hefner he had it all at one time money-fame-fortunes-women begging to fuck but some how, some wires disconnected in his brain. To do the shit he did to his body. And as they say MONEY can buy anything but don't fuck with what your mother gave you. So all the bullshit that was put in his body Im sure contributed to a short lived life to Michael Jackson. R.I.P.
