Samuel Hallett Posted 12 months ago Ron Gutman: The hidden power of smiling Smiling is great. But i think it is mostly the reason behind why you are smiling. Cause happiness shouldn't really be measured by a mere showing of the teeth. Yes, smiling could be a way in which you react to your happiness or positive feeling. If you make you life and environment positive than inturn it might increase smiling. I agree, that smiling can improve social interaction-this might be the reason why smiling more has improved an individual's quality of life through social determinants.
