Create an image of a man in his late 40s to early 50s, shirtless with a muscular, well-maintained physique. His chest and arms are strong and defined, with a moderate amount of body hair on his chest and a light dusting on his arms. His hair is a mix of dark brown and silver, giving him a distinguished salt-and-pepper look. The hair on his chest is darker but still shows some graying, adding to his , rugged appeal. He has a square jawline with a few wrinkles around his piercing blue eyes. His expression is calm and authoritative, reflecting both his experience and confidence. The lighting should highlight the details of his muscular build and the subtle signs of age that add character to his appearance.
