I study a lot of things, But Medicine and Biology, I just never had the interest, I know less about Medicine and Biology than most people. MY uncle has been sick really sick for a long time, He just found out he has to have emergency surgery. I need to ask you guys, Is this something I should be very worried about? I think people can live without a spleen, all I know is he has it, And they are sending him for surgery. Should I be worried?
