Advantage of Exercise Science and Pharmaceutical Sciences?

Hi everyone,

The Exercise Science is major, but my dad is in sales for healthcare software and so is around healthcare a lot. He believes that a double major with Pharmaceutical Sciences would give me a step ahead in helping people with their health because I would be able to evaluate them in many facets of health, those being exercise, nutrition, and also on what medications they are taking.

Does anyone have any experience in either of these fields please help me?

Thanks and regards
Andy Charles
