A fascinating study has found that sniffing female tears significantly reduced male aggression and decreased activity in aggression-related brain networks. It’s suggested that the effect, which is caused by chemical signals in tears and is also seen in rodents, serves a protective function.
I feel like they should also have experimental groups of children and the elderly, to see whether age also has an effect on hormonal responses.
I suppose that applies both in regards to tears from and how tears affect. Hmm, I can see this getting rather complicated and extensive.
I find this is my answer to most things honestly.
