When I was a child my father was visited by a former colleague, who previously had a stroke. The colleague was partly paralyzed. He had great difficulties talking and to me it looked like he had also problems thinking straight. It appeared that his brain was severly damaged by the stroke. You cannot imagine my surprise when, as he left, he went into his car and drove away just like that.
