I'm every age I've ever been - and I think will be, tho' that's
  a guess. I want to be the awesome old man with the shocking
  white hair and the wise shit coming out of his mouth, so I'm
  practicing now while also I don't want to be the old fart who
  says, "someday you'll understand" because that's usually a bit
  of BS 'cause there's stuff they said I'd understand someday that
  I *still* don't understand, so I'm still that annoyed 13 yr old
  tired of adult BS. So yeah, i could write a book about "being
  all ages at once" as you go through life but I never actually
  write a book when I say "I could write a book", so I know I'm
  full of it.
