Do You Remember Your Last Name?

i became the united states memory champion. What should you do? Come up with some sort of an association between a person's name and some aspect of their physical being. If i wanted to remember my last name for well, it sounds n awful out like t number four, i would look at myself. Again, a what color i can put into this image, the more likely it is i'm goin to remember it later. Its obviously a fun parlor trick, but have you used this in your job at all, to remember people's names?"
