How do you make a Sim younger on Life Stories?

OK, so, what you do is hold down control, alt and shift at the same time. A blue box should appear at the top of the screen, click on it and type in 'testingcheatsenabled true' no gaps apart from the one between 'enabled' and 'true'. Press enter and nothing will appear to happen but if you hold down shift while clicking on your sim and four of options will come up. Click on the one that says 'Edit sim in create a Sim and you can remake your sim! It will be exactly like when you first made your sim so you can choose their age. I love this cheat, I use it all the time and it works! You can also do the same thing but instead of clicking on your sim click on the mail box and you can choose your Sim's career or make them REALLY happy (by that I mean they don't need to eat or go to the loo or have fun) but that won't last so you will have to keep doing it.

However, I have only done this cheat on The Sims 3 so not sure if it will work on the Sims 2. Try it out and tell me!

I hope this helped!
