Over the years, viewers witnessed how Haha and other South Korean celebrities have had to endure strenuous activities that involved running, carrying cast members or guests to complete missions and other tasks. Haha confessed that he experienced having a slipped disc seven times but endured the pain since he thought that everybody felt the same way.

It was only after Haha consulted with a doctor that he learned that his health condition was nearly fatal. The doctor commented that the musician was in danger of becoming paralyzed had he not sought medical attention.

Apart from Haha, other "Running Man" cast members also suffered similar health problems. Yoo Jae Suk has had to endure with problems with his neck, ankle and waist, while former member Gary suffered from a torn ligament and shoulder pain, according to the rapper.

In other news, with the impending end of "Running Man," avid fans of the South Korean musician can look forward to seeing him on the small screen as the host of a new music competition. Haha, as well Jung Jun Ha, were identified as the new hosts of Mnet's upcoming rap/hip-hop competition named "High School Rapper," according to All Kpop.

Meanwhile, Haha and other "Running Man" cast members will soon visit Taiwan to hold a fan meeting event. The said event, scheduled on Feb. 10, will still continue despite the SBS variety show's upcoming finale, a source shared with Yonhap News.
