Isn't it possible to accept death and be sincere, friendly and in love with people nevertheless. Why is it a contradiction for you?
Always, since the profession of doctors are present, they were dealing with dying people. What happens to a doctor who cannot accept that people die? Will he/she probably become stressed out because of dying people, especially when they were young and healthy before? Why would you be different in your profession as a biologist? We are all humans and death is the most natural thing next do birth. I think we forget about it too often and once it moves itself in front of our eyes, we become deeply uncomfortable, like right now.
But okay. I think this could be something your educators could talk about to their students. If not, I would ask myself, why.
