When conducting research on animals, you have to be very careful, because you want the experiment to succeed, I’ve only conducted research on rats previously, and sometimes, we did not know why the animal died. The animals were put under so that they did not experience any pain, and sometimes we found that some of the animals would die from anesthesia. this did not happen often but we did see it. This caused the repetition of several experiments because we could not count on the ones that died. One of the ways we try to investigate the failure of the experiments was that we did a mortality rate study, evaluating in what phase the animal died, how long after the experiment, in what conditions etc. I liked that we did this because it intrigued me to find patterns in their cause of death and it was something I learned from research in academia.
