Yea, medicine is very much an obsession. I had my mom teach me how to take a Blood Pressure when I was 8 (my mom was a nurse--she's now disabled as am I). I used to try to read her textbooks and asked what this or that meant. Anatomy and Physiology was my favorite class in high school and I have my BA in Neuroscience. I was planning to go to med school, but I became very ill and now can no longer work. I have a rare genetic collagen deficiency called Ehlers-Danlos Syndrome (have fun with that one people! Fantastic info can be found on GeneReviews). I research everything, and try to learn as much as I can. My geneticist says I should do something in medicine. I would love to, I just don't know what. I don't have the physical stamina to go through med school. But like many have said here, I watch all the medical documentaries, shows, dramas, everything medicine. I love learning about how things work, especially the body and the brain. I love the complexities of the brain and how everything works. In fact my thesis in college was neuroendicrinologically based. My panel for the thesis presentation was willing to help me write a grant to be approved to extend my study into grad school. I would have had to stay in New Hampshire though.
