Human life cycle

What am I talking about?
In your opinion what are the stages of human life? I’m talking about adding on to a list that so far looks like this:

  1. Infant(0-1)
  2. Baby(1-3)
  3. Toddler(3-5)
  4. Preteen(10-12)
  5. Teen(13-19)
  6. College kid(20-?)
  7. Adult(?-60)
  8. Elderly(60-80)
  9. What’s this pool?(80-100)(Pretty old/wise)

Goals
It seems like adolescence has a pinned down number of age pools.But adults? There has to be some room for improvement.The [adult] age pool is a huge gap to overcome because it spans so long without any new pool and pools 6-7 need to have some ages sorted out(Find out what ??? should be).
Side Quest
What should we call all of these pools,demographics,ages? It would help out a lot.I refer to them as pools but maybe a new word might have to be made for this post.(Or more helpfully a fellow doper already knows a word)
How to do this
If you have found a pool just post the [pool(age-age)] and I will update the original list.
For example if you post.“Yorple (40-53)”(Yorple is a made up example) the list will look like this

  1. Infant(0-1)
  2. Baby(1-3)
  3. Toddler(3-5)
  4. Preteen(10-12)
  5. Teen(13-19)
  6. College kid(20-who knows?)
  7. Yorple(40-53)
  8. Needs new name (53-60)
  9. Elderly(60-80)
  10. What is this denomination?(80-100)(Pretty old/wise)

Rules

  • If something is bolded on the list or there is a gap between pools or there is a subdivision of a pool.That’s what we are trying to finish.
  • Age slang should not have to be apart of the list(boomer,alpha,zoomer,etc)
  • Generations should not be apart of the list because labeling for example (0-14) as Gen Alpha will become outdated in the following years.
  • You can veto another doper but only with a reason.Conflict can be dealt with in a controlled manner.
    When does it end
    The list is aiming to create a comprehensive list of stages of life.So when no additions can be thought of the page will be turned off and the final list will be posted.

This is what the list looks like so far.

0-7 Formative
8-12 Learning
13-24 Bonding
24-50 Reproducing
51-65 Wealth accumulation
66-86 Personal Realization
86-106 Reflection

20-something, 30-something, 40-something, ad infinitum

ETA - My flip answer looks pretty lame following @Crane ’s rather brilliant offering.

Willy S gives seven stages, but no years attached to them.

Toddlers are 2 or 3 years old. Not 4 and 5.

  • Infant(0-.5)
  • Baby(.5-2)
  • Toddler(2-3)
  • Preteen(10-12)
  • Teen(13-19)
  • College kid(20-?)
  • Adult(?-60)
  • Elderly(60-80)
  • What’s this pool?(80-100)(Pretty old/wise)

UPDATE :arrow_up:

That jumped out at me, too. Five-year-olds don’t toddle.

Young: newborn to 37
Middle aged: 37 to 74
Old: 74 and beyond

A more simpler way of thinking…Thanks!

If I may offer the considered opinion of noted ego psychologist, Erik Erikson:
