Volunteer during the season.

Roger Dooley points us toward a new study that purports that volunteering helps with cognition.

"Cognitive activity embedded within social settings may further increase task novelty, interactive problem-solving skills, and motivations to sustain these activities," the authors wrote.

"In addition, these activities are generative in giving meaning and purpose to one's life (volunteering, civic organizations, assisting others), which may make them more rewarding and personally enriching than highly stimulating activities performed alone. As a result, individuals may place more value on these activities beyond their immediate personal benefit and may sustain interest longer."

Basically it says, helping other people makes you smarter. What if your business donated your employees to help a cause on one day a quarter. You will be doing some good in the community and making your staff brighter in the process.
