AC/DC about to call it quits - Maybe

Sadly, I have a friend that had a stroke about a year ago. People can see the surface level conversation and think oh ok he's fine. But in reality if you question looking for specific answers you realize how far they are gone. I seriously doubt any man who had a stroke could play as he used to.
The people I know personally whom have had a stroke, have never even came close to recovering. Malcom may never be the same. It's a CRUEL WORLD!
