In recent times there have been major advancements in what is known about the causes of aging and how to help stop and prevent aging. I want to learn all I can about this subject and eventually obtain a position where I can truly help advance this field of research. I am unsure of whether genetics, biology, medicine etc etc would be best to major in for college. It seems like there is so much to it that it's hard to determine what the best path to take really is! Hopefully I can obtain a response from someone more educated than I on this.
