ty , you can also use: aging on/off 2 (de)activate getting older, but with this object no cheats needed

Yes, and where aging on/off effects all sims, this only effects the sim that drinks it.

Great hack! Thank you.

This should be great! Your mods are the best. Thanks!

Thanks Smonaff for making in. But I have a problem some times (about 80%) that sims just cancel the interaction. It might because I have pets, so could you look in to it?

Do you have the same problem with other potions, such as the love potion? The reason I ask is because this is cloned from the love potion and the 'drink potion interaction' is basically the same, so if your sims use the love potion without a problem then they should be able to use this without problems. You say they do drink it sometimes, if there was an incompatibility with Pets they would probably always fail to drink it.

Edit:
Ok, I found the problem and have uploaded an update to fix it. What was causing it was that I had the guardian BHAV set improperly in the TTAB. It didn't effect potions that were used from inventory.

Yep it works fine now! Thanks

Ok, good.

Once my sim used it, the sims on the lot lost their free will. They have to be directed to use the bathroom, go to bed, etc. I checked the free will setting, and "free will" is selected, but the sims are like zombies now.

sailorjune, are you certain that it is this hack that is causing the problem, because it works fine in my game and sims still have freewill after using it. I have seen the problem you are describing before, but it was caused by a social plugin that improperly handled autonomous sims. Think of any hacks that you may have that would add options to the pie menu that appears when clicking on a sim, in this case it would be a sim other than the active sim. Two examples of such hacks are the Period Hack and the Main Controller from the Gypsy Potions. It was actually the Period Hack where I first encountered this problem, but that was when I had first created it and the problem has long since been fixed. This is not to say that it isn't the Anti-Aging potion that is causing the problem, because what works fine in one person's game may not work right in someone else's even if they both have the same EPs. And speaking of EPs, In your profile you have it listed as only having "Original" and "University", which I assume you just forgot to update it when you got Nightlife, because without NL you shouldn't be able to use the potion.

What about dog? i am still look for it, i have life tree for sims stay age but dog went pass way oh dear i want dog stay life with me :-)

I would love something opposite to this, a potion that makes the sim age 3 days in an instant. (Like the elixir of life sometimes does if they drink it below gold aspiration).

This to make age differences between the sims more realistic. It's not really realistic that 5 sims have a birthday at the same time just because they were created into the same family in CAS.

Hope someone feels like making this!

Thank you soooo much, his is great

wow is there a way to make it so you can toast

This is perfect for my dying elders
