Kuddos to Bill Gee from South Africa for his creativity and marketing acumen! Check out his website http://www.joygym.org/
This is Laughter Yoga, only phrased differently.
Of particular interest to me on his website was http://www.joygym.org/joygym-proven-results.htm. The results shown on this page are from the toughest test possible for a happiness program – the participants were the staff and care workers at a South African hospice. These heroes care for thousands of abused, abandoned, HIV-positive, orphaned and terminally ill children, and people living with HIV, cancer and other terminal illness. As part of their work they are exposed to extreme stress, trauma and grief. Before the program most were suffering from depression, burnout and health problems. After the test, well, read the page. It’s impressive.
