They say it takes more muscle to frown than to smile .. so it’s better to smile (my parents said so too). Besides, a genuine smile will make other people happy too .. somewhat. I know everytime I see my 2-years-old Goddaughter’s smile, all my problems seem to go away immediately .. she has such an innocent smile, pure and genuine .. no pretending, she just smiles. 
And from time to time, I’d say it’s even better to turn a smile into a good laugh, because according to this article:
What may surprise you even more is the fact that researchers estimate that laughing 100 times is equal to 10 minutes on the rowing machine or 15 minutes on an exercise bike. Laughing can be a total body workout! Blood pressure is lowered, and there is an increase in vascular blood flow and in oxygenation of the blood, which further assists healing. Laughter also gives your diaphragm and abdominal, respiratory, facial, leg and back muscles a workout. That’s why you often feel exhausted after a long bout of laughter — you’ve just had an aerobic workout!
A workout! From laughing … that’s just neat.
So maybe we should smile and laugh more. Heh .. even this barbary ape knows it (LOL):
