We can appear to be tough as nails, but guys have a level of insecurity and vulnerability that's exponentially bigger than you think. With the primal urge to be alpha comes extreme heartbreak. The harder we fight, the harder we fall.

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.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
