The Person Who Influence My Career

The person that I admire the most named Thomas Alva Edison. I knew him from textbook when I was in elementary school. He was a great inventor. He invented electric light, cinecamera, generator and etc. He also did a great job in chemistry, architecture and mining. As I know, he was born in 1847, and died in 1931. I always wondering if he still alive now, what huge contributions he may make to the world! If those great scientists are still working, the world will be developed extremely fast. I want to major in Molecular Biology and Genetics, because I believe DNA and protein dominate human's life, especially the DNA. If human being is able to improve them, human's life may be longer. Which means "Thomas Alva Edison" may contribute to the world for hundred years. This is my dream. I know this is a mission impossible, but I will try it. I never try it before. How can I just give up without attempt?
