Can we have a Middle aged lifestage?

Thanks for the shout out lol of course I'm on board to me I feel like the Sims skipped the in between life stages like the baby jumping from newborn to child we had to put toddlers in the mix, then teen to adult, young adult, adult and death they had to put elders in early games now we have infants which is only a Lifestage because people couldn't pick up the newborn from the bassinet, However the gap between child and teen was always a thing for me in previous games that's why I wanted Preteens to be introduced in the game however the gap between child and teens became more prominent in this version of the Sims which I started asking for this Lifestage even more so. I asked for a Middle aged life stage because of the same reasons with the kids and how he the Sims 4 have the elders playing older then in previous games especially with the overexert and dying. 

I would also liked to add that Middle aged or Senior Life Stage can also get the mid life crisis that Adults get.
