My ideal job

I think that my ideal job could be something related with the experimental sciences. I would like discover the cure for illness and overcome people or something similar. This job can be very entertained for me because is something that I like it and I could feel fulfilled.  Inside this branch of science, you can be an astronomer, a biochemist, a physicist... Still I don't know who choose.  The advantajes of this job are the salary, help people and find new things. In my opinion, I think that this job hasn't got disadvantaje because no is a job where you can run danger, like a police or firefighter.
