Realistic Aging - Updated

Update: The mod broke again, I've updated it. There are 2 versions available, one for those with cats and dogs installed and one for those without, only install one.

Update: The mod broke with the November patch and the cats and dogs expansion, I've now fixed it. I've also added cats and dogs, they work a little differently as their age is a range rather than one number, so each pet will live to a different age. Please see below for details of the pets lifespans.

Based on sims 3 seasons where 4 weeks equalled 1 sim year. Therefore sims will age 1 year every 28 sim days. This means if you keep track you can have real ages for all your sims and know when their birthday is, e.g. if a sim is born on a Sunday then every 4th Sunday will be their birthday. Maybe a bit long for legacy play but useful for storytelling purposes.

Conflicts
This mod alters the sims.aging xml and will therefore conflict with any mod altering the same file.
