Sense

The sense that i couldn't live without would have to be eyesight. I play a lot of video games and love baseball so without eyesight my life would take a major downturn. I have also done many blindfolded experiments and couldn't imagine living that way forever.

Brain Operation

Letting someone operate on my brain would depend on a lot if factors. These would include how bad I needed the operation, who was doing the operation, and whether or not it had been tested and was a somewhat safe procedure. Although in a life or death situation I would do almost anything.

Fields of Psychology

I would be most interested in studying forensic psychology. I love watching crime shows and believe it would be fun to get in a criminals mind. I have also always been interested in what drives criminals and why they do what they do. I just find the entire forensic field interesting.

p.s. I know it's late but something with my internet messed up yesterday.
