		 There is no spark of life. 
 
The word "life" is only a term of convienience. Ultimately your body is constantly following the laws of physics. 
 
What is keeping you "alive" is the complex interaction between all of the various sub-systems of your body. Upsetting this balance will cause your body to act in a much less interesting manner (it will die). 
 
Of course you said; "I know all about the biological and chemical processes that, in essence, make our bodies function.", but where do you want to go beyond that?   
 
Life is not a "thing", there is no "life stuff". Life is a process. The process is caused by the aforementioned biological and chemical interactions. Why do you need to postulate a 'magical' component to yourself?
