Wired Science

I saw the craziest thing last night on wierd science. Well a couple of things. One was about a bank that holds human organs, tissues, etc. Obviously they are only used for science, but still.. creepy right? They were studying about alzhiemer disease and there were two people that were going to donate their brain to the study when they passed away. However the research also consists of studing the brain while it is still alive and functioning. This couple every year went through vigorous tests and studies, so the scientist could see the changes and hopefully figure out what is causing this disease. That wasn't what freaked me out. An hour after someone dies (when they donate their brain to science) the scientist takes cells from their brain and harvests them. That's right. How can you harvest something that isn't alive? Exactly, the cells even after an hour, in your brain are still alive and can be used for further study. GROSS!!! Does this mean I have a chance to live? Well no, but still the thought that something is still alive in your body after your dead freaks me out.
