Dr. Lee Wang-jae on Marathons

‌
They say marathons are addictive, and there are so many patients who develop arteriosclerosis from running them. There are even cases where people almost died and were saved by Seoul National University Hospital...
But apparently, people just can't quit. The endorphins released during a marathon make it highly addictive, and they say people's hands even start to shake if they can't run ㅠㅠ
