Three days ago you asked -- two people 'liked' - - but lots of people have missed out on some great smiles. :) They still make me feel good, just looking in at them. :)
I myself am known in internet circles as being a "smiley". I know that smiling makes a person more available to talk, to laugh more and connect better to a stranger. And another insight into that topic is that your outside responds to your inside, meaning that you feel healthy or painfree or so. Laughter is the best medicine anyway.....
