Me? Computer geek?

I am going back and forward on what to study. I am really interested in computers, science, biologi, the human body, law etc. I spoke to a guy at work about it and he gave me this book to read about Computer forensic, digital evidence and computer crime. I asked him to give me 3 weeks to finish it its about 700 pages and a lot of new words. Im gonna highlight some interesting things in the book and see if this direction fits me as well as it feels like.
