I agree with you; the military is not the type of self-discipline needed for intensive study necessary for pharmacy. It emphasizes taking orders unquestioning and leaves little room for creative thinking. I would rather see him take up Tai Tchi that combines self-discipline with the martial arts. Since he already has a high grade in karate it should not be difficult to adapt quickly to Tai Chi. Either read up about it or visit a studio where it is taught.
