Steven Tyler - Steven Tyler: 'I Have Add'
Aerosmith star Steven Tyler is convinced he suffers from attention deficit disorder (Add).
The rocker admits he is a workaholic and a control freak, and he fears his irrational behaviour is a symptom of something more serious.
In an interview with America's 60 Minutes TV show, Tyler reveals he often writes song lyrics while he is driving and adds, "You know what, I'm Add personified."
When the host asked whether his condition is more like obsessive-compulsive disorder (Ocd), he replies, "I'm not sure about that. But I'm Add."
