“I’ve been driving for a long time but I haven’t driven recently because my mind is twirling and sometimes — well, not any more on the phone but it used to be — when I would talk, think, write and I found myself turning into an up ramp of a highway and the cars were coming down and I thought, ‘that’s it, I’m not driving anymore.'”
