If I worked in the area of veterinary parasitology, I think I would enjoy it. One reason why is because I get to help animals of all kind, whether they are pets or not. The animals could be from house pets like cats and dogs to farm animals like horses. Another reason is that you wouldn't work alone because you will always have coworkers to help you out. These are my reasons why I would enjoy working in the area of veterinary parasitology.
Hope this helps.
