As a 17 year-old high schooler in Israel, Dan Ariely suffered a massive injury that left 70% of his body covered in third degree burns.

His books, Predictable Irrational, The Honest Truth about Dishonesty, and The Upside of Irrationality, are all New York Times bestsellers, and seek to explain why we act the way we do.
