What's in a number?

I have always been a fan of the visual arts particularly the genres of cinematography, film, and television.  Today I decided to pay homage to one of the greats, the classic; Sesame street's "One of these things is not like the other".

I have taken and posted a photo for 500 hundred consecutive days without any discernible effect to my mental health. Also, as can be seen here, my determination and commitment to healthy living.
