You had proposed an idea that you all could go down to the shop see if there was anything that the seller could do for you.
Still frustrated, Charlie wanted to get even with them since they are in their forties and you are still a teenager. Jeremy and Devin agreed to this arrangement. You grunt in unwillingly because you had no desire to become older, but you do owe it to them so you ask them what age.
The three previous teenagers marveled and all the various options they had. Devon had said to have you age until you were 80, but then Charlie said you would be too old to change them back. Jeremy suggested that you would be 48 but then Charlie interrupt claiming that he wouldn't really learn his lesson since that age was way too young.
Finally they decide to have you age until you stop at 56 years old. You squeeze your hand in anger since that age was way past your prime. However, you agree that it would only be fair. You set the device to add 40 years to years to your 16 year old body. Right before you press START you ask them at what rate they want you to age at. They had all agreed for you age at +0.25 years per second.
You close your eyes and press START awaiting whatever the future has in store for your body....
