I am Hunter Hillenmeyer, 8 year veteran of the Chicago Bears, Co-Founder of [OverDog](http://theoverdog.com), and concussion safety advocate, AMA.
I'm relatively new to Reddit. I have a couple things that could be fun to talk about. Concussions and their evolving role in football have become a huge hot button issue. I was a founding member of the NFLPA Traumatic Brain Injury Committee, had my career ended by concussions, and now serve as an advocate on the issue.
I'm also President of OverDog, a start-up with a Kickstarter running right now:
We are building a platform to connect athletes and fans through video games and looking for beta users thru Kickstarter. Please back us for immediate access to all our athletes.
My proof is on my Twitter handle, also @hthill. I will be back at 3:00est to start answering questions. Ask me anything!
Thanks to everyone for all the input today. I will try to answer a couple more of these later, so check back in if I didn't get to your question. Please share our Kickstarter to fellow fans and thru your social networks. Thanks again for all the great questions!!
