@Fattihunter Mods aren't really supported here, since EA doesn't officially endorse their use, and this is an official EA site (even if most of the people responding are just fellow players). I do know that there was originally a mod created to do so by Twoftmama on SimsAsylum, but I'm not sure if it was ever updated for patch 1.67. You might be able to create a tuning mod of your own to prevent the decay, or borrow someone else's.
At any rate, the best place to ask this question is at NRaas. Someone there will be able to tell you what's out there already, or how to use NRaas modes to accomplish the same thing, if possible.
