Stress v. kindness

I have mentioned David R. Hamilton before.  He has a PhD in organic chemistry and worked with a pharmaceutical company developing drugs.  He noted that in experiments there were often some people in the placebo group that did as well as those receiving a drug.  That observation led him to write "Why Woo-Woo Works" about the mind and its biological powers in the body.  He has other books on the powers of the mind.

He has a new book, "The Five Side-Effects of Kindness".  I have been re-reading "Why Woo-Woo Works" and there he emphasizes that a strong 

tool to deal with stress is kindness.  He notes that people often assume that relaxation is the best tool to destress but he says that kindness is more powerful.
