Sure, most of it is aimed towards women, but it also applies to men to some extend in the RP-sphere:

The extreme obsession with age. Hitting 30 is basically dying.

Why this EXTREME obsession with it? It's actually the most "cagey" philosophy I can think off.

It's pretty common to finish college at age 25 and older:

Graduate students are even in their 30s:

But anyway, let's keep the "25": So, at best, after finishing school and college, you have around 5 years to live. Then you're "finished" (despite the average life span nearing 100).

Isn't such a "philosophy" the surest way to get an acute deppression? We are all getting older, how can such an outlook have ANY fans at all?
