Pre-teens and mid adults BG update

Personally I'm good with the age groups that are, but I would want them more fleshed out and different. For instance teens-elders are almost all the same - the same aspirations, the same clothes, the same skills... Teens have a bit more to flesh them out if you have parenthood, but otherwise not really.

• What if there were aspirations that were tied to each life stage, only available for those life stages?
  
• What if there were activities and social interactions that were age specific?
  
• What if whims were different for each life stage - and more prominent for some life stages (i.e. tied to impulse control which increases with age)?
  
• What if the needs were different (decayed at a different rate) for each life stage? Such as need for social interaction being greater for teens and young adults than the other ages, or focus as a mood lasting shorter periods of time.
  
• What if social relationships decayed at different speeds at different ages? Teens would form friendships and romances really fast - but they'd decay fast as well and quickly turn to dislike with an argument or two, while adults and elders would form friendships and romances much more slowly - but they'd decay much more slowly (or not at all when reaching the elder stage).
  
• What if there were more activities tied to elders, especially tied to grand children and taking care or spending time with them?
  
• What if there were traits that were gained from aging up that are previously hidden? Things like grandparent trait - the sim can then nag kids about having kids of their own. Tell their kids how to be a parent. Spoil their grandchildren. Brag about grandchildren. Grumpy trait - the "keep off my lawn" kind of elder. Bitter - for those who didn't have a good life or spent much time unhappy or didn't fulfil their aspiration, or the other way around for someone who has lived a fulfilling life...
  

So no, I definitely do not need a mid-adult stage, and while I could live with a pre-teen age I don't really need it. Just give me better ages of the ones we do have. Especially to our elders!
