I had to have a minor in grad school and chose Comp Sci. The use of computers to gather and process lab data was just starting and I thought it was a good minor. We also had a foreign language requirement, and knowledge of a computer language fulfilled it. After a couple of years as a physiology grad student, I was tired of killing things and didn't really like the future path ahead of me. So I made my minor my major. It was one of the smartest moves I've made, probably only second to deciding to go to work for Stratacom rather than ACC (Advanced Computer Communications) in 1996.
