Research topic

I tend to be incredibly indecisive when it comes to most things so picking an exact topic is going to be difficult for me. I think I probably want to do something that relates to organ failure or artificial organs but I actually really don't know where to start. I wish I had more experience with research papers and research in general. I feel a little out of my comfort zone. The only essays I ever wrote were prompted with questions usually about books that I read. So I guess these are new waters for me. I will think more about this later.
