Want vitality? Take political action.

That's the conclusion reached by British psychologists in studies described in a recent article in the Guardian.

They studied college students and found the happiest ones were politically active.

Reporter Aditya Chakrabortty notes that the study flies in the face of the popular wisdom that happiness
resides in creature comforts and relative affluence. Perhaps
activism gives people a sense of purpose, or of agency or
just a chance to hang out with other people. Most likely it
does all of the above.
