The first thing that happened to me was I found my disease by chance. When I was a middle school student, I almost lived in the schoolyard to play baseball and soccer. And then, one day I was taking classes, I had a backache. The pain continued even after I got home, so my father told me to go to orthopedic. Stupidly, I thought I was ok because I used to get tired and sick the next day after playing hard. And of course I wanted to play with my friends more than go for treatment. But the pain was long and I went to orthopedic, and Doctor told me something that I unexpected. He said I had a disease called Spondylolysis. It was not simple muscle pain but a pain in the back that caused by the compression of the disc. If I continue to play too much, my spine could be pushed forward. And if I hadn’t went to orthopedic, I could have been in trouble.The second thing that happened to me was car accident. It happened in the evening after I finished my academy. I came home, but my family was going to eat 곱창. At that time, I was very hungry and I liked 곱창 so much. So I rode my bike to get there as soon as possible. I went by complying with all the traffic regulations I had to follow. But as I was passing the crosswalk, the car that was turning left bumped into my left body. Luckily I wasn't hurt anywhere. Do you know the saying, "What doesn't kill you makes you stronger."? For me, "What doesn't kill me makes me careful about everything." After the accident, I couldn't ride my bike for a while and I saw the cars several times before crossing the crosswalk. If I hadn't had an accident, I wouldn't have lived as carefully as I do now.
