I think you said it best...
“Trust not your eyes, they can deceive you.” Believe me I am very discriminating about posting any photos of myself. I think the day I took the avatar photo I must’ve taken about 25 shots before I found one I thought was flattering enough to post. Also, I think that picture is at least a year old so yes, I was a baby there. :)
But consider this...
MY avatar photo is even older. Check the hair color just in case you haven’t noticed.
