Half Correct.
Meatloaf, like many other rockers of that era, were pretty hard on their bodies... in addition to his obesity, he had asthma, and had collapsed several times on stage. He was a smoker, and admitted drug and alcohol user. I believe he also had a stroke a few years ago.. I saw him in an interview with Dan Rather last year, and he could barely talk.
One of my all time favorites... will be missed. Both him and Jim Steinman....
