There are many ways to optimize our humanity.  Alex Honnold (sp?) represents the epitome of optimization from a flow state.  some optimizations are proven beyond a shadow of a doubt, vis-a-vis Dr. Weil's 365. Some have less research as in some of the Photo Bio Modulation techniques.  Regardless, if an optimization can help and if there is no downside, then why not implement it?  This is my governing principle.  If it does not harm and it MAY be beneficial then I am willing to try it.
