Colin Kaepernick

My dad, being a businessman, constantly talked to me about carrying myself in a certain way and treating people with respect. And I think that's something that's carried over throughout my life. It's how I deal with certain situations.

My parents told me from the time I can remember that, 'Yeah, you're adopted. But this is your family.' I can remember my mom, she tells me this story: when I was little, I was looking at her, and I was like, 'Why isn't my skin the same color as yours?' She was like, 'Oh, you're adopted, but I wish I had pretty brown skin like you.'

The closer I get to retirement, the more I feel it will be a huge change, a shock, because athletics has been the core of my whole life. I know I'll miss the feeling of running fast, the adrenaline rush, and hearing the crowd cheering me on.
