I've aged into the reference points of youth

[SecularIslamist]

Experiences of an oldcel:

• The football / basketball / NFL etc team are full of people your age and your age is no longer 'young'.
• Movies you grow up watching, the age of the actors you considered 'grownup' were the same age you are when it was shot.
• You start seeing more and more politicians your age entering parliament / Congress
• Your cousin/nephew is now entering X grade and you remember it like yesterday and you also remember him as an infant.
• The MILF category starts to have women your age and your fave pornstar is doesn't look as good / retiring.

Last one is the final boss of aging.
