Tom, thanks for the throwback picture!  It's quite remarkable to see how variations of beard length alter our appearance so dramatically.  I've grown accustomed to seeing your avatar picture, but the throwback is still a very full and thick short beard; yet the change from there to your current beard is a much greater contrast, than the difference between clean shaven to throwback. Well, I guess this helps me to understand how those around us can become unfamiliar with our appearance, as our beards grow quicker than their ability to digest these changes to our countenance.
