Is my antimatter self asking this question backwards right now?

Stephen Hawking and other astrophysicists note that the world we know is the result of the small portion of matter that withstood the collision between matter and anti-matter when the universe formed. Besides the fact that I was once a much larger mass than now (making us all that television show’s ‘The Biggest Losers’) how can there be an anti-matter me, as Hawking contends, if my existence is part of the winning speck of the ‘matter’ side of the collision?
