Eric recommends the following next steps:
Let me be direct. The human body obeys the laws of physics. STEM allows you to understand this. Just about anything dealing with the human body will allow you to understand it better with a background in STEM. Kinesiology, for example, is a great degree to take advantage of this knowledge. And many more. In my own studies in exercise physiology and kinesiology, my knowledge of math and physics made it very clear. Go for it!
