The Winston School San Antonio will hold its 24th Annual Learning Symposium this Friday.

The theme of this year's symposium is "Ignite The Spark," which is the connection between exercise, proper nutrition and the brain.

"If a person has a tendency just to eat junk food, it is counterproductive to energy and it can affect in how you might perform in the classroom," said Charles J. Karulak, headmaster of Winston School San Antonio. "A lot of sugars, you may have a high for a period of time but then it wanes quickly."

This symposium will cover several other topics including sleep disorders and social media, raising and teaching children in real life and online.

It is open to the public, and will be held Friday from 8:30 a.m. to 4 p.m. at The Winston School San Antonio campus located in the Medical Center area at 8565 Ewing Halsell Drive.

The keynote speaker for this year's symposium is John J. Ratey from Harvard Medical School. Click on this link for registration and cost information.
