Tylenol for "social pain"

A University of Florida study says that acetaminophen (Tylenol) is good for your pain, even your "social pain" from hurt feelings.  Apparently, social pain and physical pain use some of the same biochemical pathways. The study found that "people who took acetaminophen daily for three weeks reported less emotional suffering over time." Also, "because research has found that being rejected triggers aggression, using acetaminophen to alleviate emotional distress could reduce the likelihood of destructive actions." So maybe Tylenol is all that is needed to prevent workplace shootings. We should put it in the water.
