“Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around.” Leo Buscaglia.
Touching others releases oxytocin, the love hormone. Even if you don't have a partner to love and touch, hugging friends and children or stroking pets has a similar effect. People love people who are warm and empathetic so don't hold back. Just touching someone on the arm as you talk to them makes an impact and causes them to remember you and like you more.
