Today, January 21, is National Hugging Day. (I know, I didn’t know either.) While the day was created to foster more public displays of emotion and affection (PDA), it’s something I was taught not to do. However, hugging and similar warm human contact is considered good for one’s emotional well-being. So hug somebody today. Preferably someone you know. After obtaining some indication of their consent. I don’t condone uninvited indiscriminate or profligate physical contact with complete strangers. In this day and age, that could be downright hazardous to your health.
