Excellent @xiore, Studies carried out on the smile declares that laughter can give us a new focus on the situations in which we find ourselves, since they activate our prefrontal cortex. This area is responsible for the most developed human functions, such as creativity, perseverance, more flexible thinking and organization.
«The most wasted day of all, is one without smiles. «A smile costs little but it is worth a lot. The one who gives it is happy and the one who receives it thanks it. It lasts only a moment and his memory, sometimes, lasts a lifetime »
