What will I study?

Well, I've benn thinking a lot the last weeks. After visiting two universities I've had to think a lot in what will I do in a near future, and I don't really know what is it going to be. First of all I'm sure that I will study in Barcelona because I already have a flat there and is the best way of not wasting to much in a place where to live. Then I'm also sure that my degree will be related with physics because is what I'd like to carry on studying. I thought about doing a degree of physics but, looking to the future jobs they're not easy to get so I'm trying to find other alternatives. After that I told myself "What about being a doctor?", but I've got a lot of problems with touching other people's injuries and all that stuff. I also thought in biomedics, but it has no physics so I left the idea easily. Now I'm thinking about biomedical engineering and Although I'm not really sure, I think that will be the best choice because it's one of the best degrees now, because it's completely new and It has a 89% of possibilities of getting a well paid job after finishing the career. So, let's see what's gonna happen!
