I went to one of the worst high school - in terms of security and students assistance - and gave them a Playing Class once a week for almost two months (7 classes of 1:30 min.) as an experiment for my recently created Foundation and all of their grades when up, they stopped stealing from each other, they learned each other names (amazing but they didn´t talk but between their small circle of 4 or 5 people. The principal of the school, who was a little resistant at the beginning, told us to comeback whenever we wanted, any day of the week, at any schedule good for us. Great! now I´m working on getting funds so I can keep going with lots of students to show them how does their brain work when happy and also the opposite.
