The age you reach when if you find an old photo of you and it is sepia toned and no one is surprised.
I just found a picture from high school and asked my wife if it was weird that it was all yellow and she said "it's 30 years old you dingus, of course it would be sepia toned by now. Congrats, you're officially sepia years old."
