Man crossing Europe hoping for reunification of Korea

Choi Chang-hyun has traveled some 13,000 km through 20 European countries in about a month in his power wheelchair. The trip has not been without adversity: "When I travel these bumpy roads in Europe, I get excruciating pain in my teeth. I have to hold the control gear for my wheelchair tightly in my mouth and it puts such pressure on my throat and back that I can't sleep at night." But if he can do this, he reasons, Korea can unify as well.
