It's very good for you, riding. You know how every model is like, 'I do yoga.' Well, I find horses to have the same effect, in that you have to put your ego aside and concentrate on making the horse do the things you want it to do, and move in the way you want it to move - particularly if you're doing dressage.

Even fictional characters sometimes receive unwarranted medical opinions. Doctors have diagnosed Ebenezer Scrooge with OCD, Sherlock Holmes with autism, and Darth Vader with borderline personality disorder.

If you're a woman doing classic theater, the big roles are often destroyers. I've played Hedda Gabler, Lady Macbeth, some of the Chekhovian heroines, Electra, Phaedra - they're all powerful women, but they're forces of negativity.
