Growing up on a farm, I saw that if I didn't go to the military or go to school, and I knew my mom and my family wasn't going to be able to send me to school out of their pocket, so it basically came down to athletics. I knew I didn't want to work on a farm. I knew I didn't want to do manual labor the rest of my life.

I've said numerous times the hardest job in America isn't being a professional athlete. It's not being a matador or having some job that puts your life at risk. The hardest job in America is being black, because it's the one thing you can't outrun.

Colin Kaepernick had a... maybe he had an epiphany. Maybe he had a realization that 'I have a higher calling the playing quarterback for the San Francisco 49ers.'

When I went to the Pro Bowl, I went as a tight end. When I made the All Pro team, I made it as a tight end. When they introduced us and I ran out of the tunnel, they introduced me as a tight end. So how is that possible that now that my career is over, they say, 'Well, he put up stats like a wide receiver?' It's not my fault I was ahead of my time.

Here's how I look at it: Life is full of challenges. Everybody has them. For some, it's health or family crises. I had a financial challenge.

The tremendous acquisition of basic knowledge will allow a much more rational treatment of cancer, viral infections, degenerative diseases and, most importantly, mental diseases.

Our purpose in this project is to begin to turn that fear of cancer, actually America's greatest fear, into a future, not only free of fear, but full of hope.
