Funny how true this is really.

Can't intentionally smiling release the same chemicals in your brain that are released when you are happy about something in a sort of backwards effect?

Fake it till you make it? I definitely think this helps in case of happiness, since a 'deliberate' smile makes folks around you friendlier and happier. That, in turn, enforces the same emotion on to you!

It's more a case of doing something everyday, eventually you become that thing. It's just a matter of time and consistency.

Faking happy could very well be one of those things.

Yes, causality as it is often talked about is a lie or more accurately a deception of the mind a cognitive bias.
