Not only does smiling make you more attractive to potential suitors, but it can also make you appear more attractive to anyone who is around to witness the act. Since interaction seems to be much easier and more enjoyable when you're smiling, others will see your happiness as an attractive quality and want to be around your positivity all of the time. Further, the muscles that you use to form a smile can also smooth the wrinkles on your face and make you appear younger.
