Try zooming in on a different area of the photo, for instance his face. You'll also see horizontal and vertical lines. They are artifacts of the JPEG compression.

Thank you. I did try what you suggested and I did indeed see what you said I would see. Now, let me ask you to compare that to the line I observed in the red circle and its interior. Was this due to compression or editing?
