When I was a wee lad in high school and deciding what to be, I decided I wanted to be a biomedical engineer. The field fascinated me and I was thrilled to one day develop bionic limbs for people who needed them. The study of electric eels and how they work was another area of intense interest. I imagined coming up with systems which could perhaps power bionic limbs the way this amphibious creature (I think electric eels are amphibious anyway) does.
Then the unthinkable happened... I saw the starting salaries. That about did it and I then decided to be a medical doctor. Somehow this career path morphed into computer science - not for the salary but I just got hooked.
All this came back to me as I read this article on the state of bionic limbs and body parts which you may find interesting. I must admit, I am more interested in IP communications now than bionics but diversions are always nice.
