Post Graduate studies

When someone talk me about what kind of post graduate studies i will choose. i get a huge fear, this kind of decision it's very hard, in special for us, because we barely start our university studies, and we don't know, what will happen in the future, what kind of subject will like us in that future, or if we will stay in ours careers, because of that start to think about ours post graduate studies is kind a messy decision.

If i had to choose, i think that genetic or toxicological studies will be my post graduate studies, why? because the genetic it's so amazing!! i think that subject in particular, it's one of my favorite subjects in all my entire career, and toxicological studies.... because i think that will be helpful if i try to find a job in the future, because this area it's very important in our times, like in the hospital, they need people with toxicological studies for the drugs that they use in the patients. I will like study this areas in other country, not in Chile, maybe in Canada or France, that will be lovey, and i prefer study this in a blended system, i think that is more easy, and practical, in special with the times, maybe get a job mean while i get this post graduate studies, i don't really know, i don't think too much about it.
