Passage: Lee started auditioning and landed minor roles in several television dramas such as Nonstop 5 and Recipe of Love. His official debut role was in an EBS series, Secret Campus (2003). Early in his career Lee went by the stage name Lee Min because his agency thought his birth name was too ordinary. However, as his stage name was pronounced and written (Hangul) in the same way as the Korean word imin, which means "immigration", he later said it was difficult to find himself in internet search results. He eventually went back to using his original name.In 2006, his acting career was put on hold for a year following a serious car accident, while riding with fellow actor Jung Il-woo. Lee was severely injured and spent several months bedridden. Upon recovery, Lee received his first leading role in the high-school drama Mackerel Run in 2007, but the series was reduced to only eight episodes due to low viewership ratings. In 2008 he appeared in various roles on television (dramas Get Up and I Am Sam) and two movies, Public Enemy Returns and Our School's E.T.. During the shooting of the latter he became good friends with actor Kim Su-ro, who later praised him on a variety show: "I recognize a star when I see one. When I was doing Our School's E.T., I knew that Lee Min-ho would become one of the top actors in the country".

Question: Why did Lee Min take a break from filming anything in 2006?
