Today San Francisco officials hosted hundreds of young kids for some fun in front of City Hall. Officials are highlighting all the different city programs offered for kids in order to keep their brains engaged during the summer.
"Learning a new sport or learning a new skill engages the brain and it actually helps a young person develop all those pro-social behaviors," Department of Children, Youth & Families Maria Su said.
A recent study found kids forget about three months worth of instruction during the long summer break.
Brain drain is even more pronounced among low-income kids who don't have a chance to attend camps or visit museums.
