study tips:

watch the magic school bus when you are learning about the immune system. 

it will make you laugh, and then you will be more appreciative of your white blood cells. because you know that if a bus full of kids somehow found their way into your body, they will chuck antibodies at them, and try to eat them. (Although technically  if you had a bus full of kids find their way into your body, the only way your body could throw antibodies at them was if your bone marrow was creating B lymphocyte cells that had the proper receptors. To much?)

the magic school bus teaches me more than my teacher.
