Postgraduate studies

When I applied to study Biochemistry on this university, I didn't though about what kind of post grade studies I will choose to study after my graduation, be cause it hasn't no sense, I think this is not the correct time to think about it, I don't know nothing concrete of the career, so I think that is too soon pay attention to things like that. My preferences, skills and knowledge will be increasing in the future and at this time I will have my full conscience paying attention to that thoughts. 
However I have to write about what kind of things I could study in the future, in that far, far, beyond, future, where I don't know nothing about and also I have to write for what things I might consider I'll be doing in this hypothetical future.
So, I can't say stupid things like " I might consider I'll be studying or doing X thing" be cause I can't see the future and it's stupid believe in some self projections. Then, I will say, I'd like to study and work on the neuroscience area. I have good friends with the same kind of projections so, I think the best thing of the science research is the teamwork and with friends are better than work alone or with people that I don't know.
I think the neuroregeneration is an unexplored area of the biology and the work of the biochemistry can help in that area. Neurodegenerative diseases are so troublesome for the actual medicine, and if we can study how the proteins, nerves, and cells can be reanimated from a permanent inactive state we can cure diseases in the spinal tap, or invalidating diseases from accidental events, even a stroke can be completely cured with the right knowledge, so for me this area are so interesting to study in a hypothetical future. I might consider I'll be doing research and studying about proteins or clinical biochemistry, with knowledges of neuroscience and neurological anatomy and physiology. The place I'll study my post grade I don't know for now, there's so much time to decide it, but I think I can do that in this university immediately when I will be graduated. That's all I can say about this theme.
