malcolm gladwell confirmed the intuition that your face reveals your emotions before you are even aware of them – now it turns out that may work both ways: a small pilot study shows that women injected with botox paralyzing solution around their frown lines showed less symptoms of depression, and not because they felt more beautiful but because of a feedback loop that directly connects facial muscles and emotions in the brain. think of all the other possibilities: if you can’t yell, maybe you won’t get angry; if you can’t stick you tongue out, you can’t be disgusted; if you can’t pucker your lips, you can’t fall in love… no doubt more studies are needed, but it’s confirmation that radiating happiness is good for you.
