You quickly run up to your room to and look for your boxes of old kids clothing. Smiling, you quickly reach up to the shelf one of the boxes is on. You can barely reach it, then suddenly you can't. Everything in the room grows bigger. Strange.
Looking in a mirror, you see a six year old staring back. You just regressed two more years!
You feel yourself starting to panic. What if you keep getting younger! You could become a baby, or unborn! You may have to go through your entire life again! And you're still naked!
You're not sure what's going to happen. The condition might stop on it's own, but if it doesn't, there might be something in the basement that can fix it.
