Having a series of heart felt chuckles a day, can lower the levels of stress hormones in the body and increase the endorphin levels in the brain. These are the same 'feel good' hormones produced in the brain after having an exhilarating and intense workout; whether at the gym or having a walk or run at the park.
Interestingly enough, laughing is also free!
You don't have to pay a monthly fee to laugh...you can feel good whenever you want to! Ironically, the more you feel good the more you attract more things that make you feel good into your life, and the more you are likely able to achieve your short term and long term life goals.
