You'll start stagnating and noticing flaws or cracks in your appearance around 22, but you can ignore them by tryna stay healthy.
Around 23 you'll go into a depression slump that you never come out of. You'll drink a lot and pretend nothing is happening.
At 26 you'll be unable to ignore anything any longer. You'll attempt to take drastic action via career choices, hrt, or unrealistic death fantasies.
At 30 you'll actually get up the nerve to neck yourself or be too broken to fight anymore.
