What Makes "You" You?

Ummmm...My DNA?
This is today's question in my Q&A a Day: 5 year Journal. I'm having a hard time answering it so I'm giving you the question. What makes "You" you?

Great shot - love the edit on this - and agree that's a tricky question! Think I need at least a day to think of a clever answer to that one!

nice shot , and it's the sort of rotten interview question that gets asked - very difficult to answer that one
