"Do All These Deaths Have To Do With 2012?"
No. Lots of people die every day. People have died every day since humans first existed. Death is just part of life, for humans and animals alike.
"ALL these deaths of major people."
Well, I wouldn't consider MJ a "major" person anymore, considering that he hadn't had a hit for 20 years. And did anyone know Ed McMahon was still alive... ?
"A big shock, and really Big."
I wasn't really surprised to learn of any of those deaths. Farrah was in very poor health, unfortunately. MJ was a fucking nut. And McMahon was just old. So, no major surprises that they died.
"Everyone's going to die at 50?"
It isn't unusual for someone to die at age 50. In many countries, the average life expectancy is shorter than that. My cousin died of leukemia last year at 52. So it happens, unfortunately.
Also, why do you call McMahon the "king of infomercials?" Other than those stupid "Cash 4 Gold" ads, I can't recall McMahon advertising anything else for the past 10 years. Wouldn't the king of infomercials be someone like "Rich dad" Kiyosaki or the Ginzu steak knife guy?
