Park Manson's 75-year-old patient, Man-Yong Jeong, challenges the 600km territorial land.

Why did he, a patient with incurable disease, go on to challenge the end of the country after completing the marathon two years ago? Jung was diagnosed with Parkinson's disease in 2012.

A typical neurodegenerative disease, Parkinson's disease in which nerve cells disappear and cause abnormal brain function, and the hands and feet tremble and the body hardens.

I went to a foreign country and received various treatments, but my illness was hardly improved.

He said that chopsticks were difficult, and he continued to delay his illness little by little from two years ago with steady herbal and rehabilitation treatments, and challenged the marathon.

At the Chuncheon Marathon in 2018, he finished his life in 5 hours and 48 minutes, and faced a crisis that almost killed him with hypothermia.

It was a difficult experience, but Jung said that he was on the road again to give hope and courage to the patients suffering from incurable diseases.

He said, "It is not a miracle to walk on the water, but a miracle to see and walk in a beautiful world."

This week, SBS <Newstory> covered the 75-year-old Parkinson's disease patient Man-yong Jung, who challenged the end of the country, walking 600km from the village of Haenam to Seoul in 26 days.
