Idk still thinking

I majored in accounting- I may like it idk. But I've found I'm fascinated by the human body. Diseases, sickness, trauma. It's really all I look up in my free time. Like ive been fascinated by Charlie Kirk's death. As weird as it sounds. The reasons for the way his body behaved, I love learning about it, how a bullet can cause cavitation and the shockwaves can destroy even more muscle. I don't want to do doctor obv, way too much schooling but I wonder what else I could do that makes a good living. I want to spend my life helping/donating to dogs. You need money for that
