Apparently you can replicate the feeling of smiling by placing a pen in between your teeth.
Supposedly your body can’t tell the difference between a fake smile and a real smile so it triggers all the same emotions.
So if you’re feeling sad and want to feel happy you could potentially fake it til you make it.
The only flaw is the voice in your head ruining everything by constantly reminding you that this good feeling isn’t genuine.
Therefore if you can quiet that voice you could control your mood and you can practice silencing it by putting a pen between your teeth!
(I’m not saying you should be happy all the time but if you find yourself sad at an inopportune moment it would be extremely valuable to know how to turn your mood around).
