Physics 10

I know I am a living system because...
Well all the evidence is not yet in and i am not convinced i truely exist. There are all these frayed, fried, and fantastic ways to construct some idea of a self and all of me is some how validated through external apparatus. I can neither prove nor dis prove my own existence.
As for BioPhysics...
Bio-life and physics-the science of matter and energy and the interrelationship of the two. Is there anything other than biophysics? Even imagined experiements are a part of nature.
