A smile is a curve, that sets br everything straight. Use it, br when you can and don't be br irate. Let your hair down, br once in a while, purse your br lips and then, smile. It will br not alter your looks, in any br way, or crinkle up your face. br It makes you look a lot better br and puts you back, in the br human race. No one likes br looking at a dead pan all br the time. It has a negative br affect on you.
