"I think I'd like to be 9 years old again." Sam stated.
"9 huh? then you have to go back to elementary school." Glen replied.
"OK, lets start" says Sam as he enters his new age into the computer, "Hold it, It says enter "change duration" and "change time""
"Hmmm... Change duration must be how long it lasts, and change time must be how long it takes you to change."
"Alright then," says Sam as he enters "forever" for change duration" and "2 min" fo change time, and presses enter, "I've set it so that we remember our lives now, but also know our new lives."
Soon, Sam felt a tingle all over his body. His slightly fat gut shrank away as he quickly lost height. He ran to the bathroom and saw himself in the mirror. He looked like he did when he was thirteen. Glen followed hime into the bathroom with the chronivac so they could watch the changes.
"What's happening?" Sam said, shocked at his new higher voice as he passed 11. Soon all, his body hair had completely retracted and he lost around 18" of his old height. He was really nine years old!
"WOW! This thing is awesome!" yelled Sam, with glee.
"Now what should we change?" wondered Glen.
"I dunno."
