Those wacky Russians..

Feeling down? Planning to end it all? Well stop right there, for the marvellous scientists of Siberia have the answer to your problems - all you need is a good whipping

"The absence of the will to live is caused with decreasing production of endorphins - the substance, which is known as the hormone of happiness. If a depressed individual receives a physical punishment, whipping that is, it will stir up endorphin receptors, activate the “production of happiness” and eventually remove depressive feelings."

Or, you know, you could go for a walk, that should get the endorphins going too...
