In an interview with the Daily Hurriyet, Turkish man Gürbüz shares that at 41, he had seriously injured his spine, leaving him paralyzed from the waist down. The incident had doctors believe that he would never be able to walk again. However, instead of drowning in his sorrows, Gürbüz had another plan, and decided to use himself as his own guinea pig. In his 'experiment' he convinced his friends to crack his vertebra bones in his spine, to move them back into place. Gürbüz says that in total, he conducted '63 experiments' on himself for nine months, after which, he was able to walk again.
So, I bet that you cannot wait to discover his secret!
