Mr. John is an elderly man in his late 70s, with a frail, thin frame. His face is weathered from years of hardship, with deep lines etched into his skin. He wears tattered clothes—an old jacket with holes, thin pants, and worn-out shoes. His beard is scruffy, and his hair is unkempt, showing the signs of living a difficult life on the streets.
