“<p>I had my four-graft heart bypass surgery on 18 September 2026. The doctors performed the operation while my heart was still beating. After surgery, I was kept under close watch and later moved out of intensive care. I slowly started walking and doing breathing exercises. I was discharged on 26 September, eight days after surgery. I stayed in Hyderabad for a check-up before returning to Papua New Guinea. I was also given medicines and advice for my recovery at home.</p>”
