Brazilian football legend Pele has moved to reassure fans that he is in good health as he continues his fight against cancer. The 81-year-old posted a photo on social media in which he is seen smiling alongside his wife Marcia Aoki at their home in Guaruja, outside Sao Paulo. "I'm sending this photo to you, just to say thank you," he said in a message accompanying the image. "I am so grateful for having my wife with me, for the laughter, for the peace of my home, and for all your loving messages. I am doing very well and taking care of my health."
