Oh wow, that old man in your neighborhood sounds really strong, from what he used to do before now. It's amazing that he's still so strong and works hard for himself. But it's also sad to hear that he's experiencing pain in his legs, waist, and has trouble seeing clearly. It's one of the challenges with them, they don't want to seem helpless so they keep arriving. I hope he would accept care from those around him. All the best in the contest.
