Nice views and thoughts. In regard to your question about "what" is my sense of humor, well I am guessing the answer depends on what you mean specifically by "what". Do you mean it as literally in what is the science behind it, or in how it may differ from yours or anyone else's? Plainly, it is an sensitivity to making things seem funny, and the various ways of emotional delight, but not without any other purpose than to to amuse . It is is here within me I suppose, or is it simply an action that is internal, or is it somewhere gone on vacation for the moment during periods of seriousness?
