The guy probably never ate at McD. He had too much money to do that.
Also, heart disease kills a huge number of people every year. It's supposedly the number 1 killer of Americans, though I'll bet it comes in second to "natural causes" whatever those are.
Anyway this isn't ironic and it's pathetic that you guys are enjoying his death... he hasn't done anything to harm you. He accomplished that which makes America great, growing business and providing jobs.
Now if you could post a link to someplace that says he ate the big mac that he put on the menu every day... that might be ironic.
