It is remarkable how much effort a human will go through to achieve a few brief moments of satisfaction.
Athletes work and struggle constantly to achieve a few moments of glory on the playing field.
Even a man, if forced to it, will put up with hours of monotonous foreplay to achieve a few moments of genuine sexual gratification. The fact of the matter is that almost anything worthwhile requires an investment of time and effort that, objectively viewed, seems out of all proportion to the final result. Thanksgiving dinner is a case in point. Indeed, as one surveys the table at the end of the traditional meal one wonders that so much preparation time could have turned into a field of debris in such a hurry. For the cook at such an occasion there is always a post-meal let down.
