Most of the Millenials I know have even already the scary 50 approaching from behind.
But that's some kind of observation bias, as I am GenX and interestingly know almost no people born between 1990 and 2000.
But I know a bunch of GenZ again who currently look like deer with big, wide open eyes at the approaching headlights of the "30" truck, which imho is much worse than the 40...
