Being a scientist especially a biological scientist like me, really helps because you can take care of yourself based on the knowledge that you have. You are able to understand the different bugs that exist in the environment and how to prevent yourself from getting them.
Being a scientist is also a lot of fun because you get to solve life problems and impact so many people. Just think about the food that you buy from the supermarket from the bread that uses yeast to the healthy yoghurt that has beneficial microbes science is everywhere.
