Also this hour: UT Southwestern’s Brain Institute recently launched a study to advance understanding of how participating in college sports and resulting concussions can affect brain wellness later in life.

Then, we reflect on 20 years of events at NRG Park with Ryan Walsh, CEO and executive director of the Harris County Sports and Convention Corporation. 

And we learn why Houston is one of the best places in the country to learn to be an entrepreneur.
