what is some information you can give me about dolphins treating the peoples depression?

"Swimming with dolphins appears to help alleviate mild to moderate depression, researchers have found.
A University of Leicester team tested the effect of regular swimming sessions with dolphins on 15 depressed people in a study carried out in Honduras.
They found that symptoms improved more among this group than among another 15 who swam in the same area – but did not interact with dolphins.
The study is published in the British Medical Journal."
