According to Sesame Street Magazine, October 15th is National Grouch Day — a day for all Grouches to celebrate their way of life.
According to the Muppet Wiki:
“A Grouch’s mission in life is to be as miserable and grouchy as possible, and pass that feeling on to everyone else. Only then will a Grouch feel in touch with his or her world and be happy. Yet, even though a Grouch may show happiness at anyone’s misfortune (including his or her own), a Grouch would never admit to being happy. Such is the stability of a Grouch’s life: so balanced, and yet so unbalanced.”
According to Therapist Julie de Azevedo Hanks, author of The Burnout Cure: An Emotional Survival Guide for Overwhelmed Women, people who are moody or pessimistic may be at a health advantage.
Research has shown that older adults who are pessimistic about their future actually live longer and are less likely to live with a disability, Hanks says. And people who tend toward pessimism may use negative thinking as a motivational strategy.
“While they may be a drag to be around, they may actually be trying to improve themselves.”
