If you're telling me that pegging the emotional barometer to "happy" all the time is healthy -- then I disagree.
We're the product of many experiences, and a monotone level of "happy" is not only artificial, it robs the soul of the sophistication and annealing that happens when you surmount difficult obstacles.
You might as well ask a coin to have only one side. It doesn't make sense, and I don't trust plastic people that pin large smiles on their faces all the time. It isn't real, and it isn't healthy.
Nah, I didn't say that.
I think I know what you're talking about, and I mostly agree about "fakeness," but let me present an alternative point of view. I enjoy being friendly to others. It makes me happy. So, when I am down... I still smile at others, and try to treat them well. It helps me to be happier, and I hope it helps them to be happier too.
I don't think that makes me fake or "plastic." I hope not.
That's why I used the conditional statement "If" at the start of my sentence. You didn't mean it that way, that's fine.
While you are correct that mimicing motions of joy can be used to reverse a bad mood, I'm more of the mind that we need both sides of the emotional spectrum to function properly.
There are benefits to every emotion, positive or not.
