IV. HOBBIES I enjoy scuba-diving and skiing, they have something to do with one another although I cannot define it exactly. I also play jazz (tenor saxophone) together with three friends of mine. Mostly classic stuff: standards, bebop... My favorite musicians are Sonny Rollins, Art Pepper, Dexter Gordon and Ben Webster.
