The local Adventure Science Museum (I imagine it's a city-by-city thing, though something of that magnitude is hard to qualify as a "franchise") has a wing devoted to the human body.  (My boys and I especially enjoy sliding down the digestive tract, which deposits people with a huge, wet fart, but that's beside the point.)  They have a digital aging station where I can see what I'll look like twenty years down the road.  Apparently, my barbers and genetics are incorrect, as I'll be mostly cue-balled at that stage.  I'd stress about it, but stress often makes people's hair fall out, and that's about as self-fulfilling a prophecy as I can do.  To test the validity of these futurific imaging devices, I think they should be required to show me an image of myself twenty years ago.  If the picture doesn't show me in high school, then the aging software is worthless.
