That isnt how ages work.

Who even thinks that??
I'd say 70 is when your really getting there

Many young people act like 40 is old age (while its considered too young to be even middle aged) and think its the age people die or smt

That's just idiotic ignorance, yet another example of the dumb generation I'm gonna have to put up with as an adult

I once saw a video where a 67 grandma in an online game says "I'm actually super old" and someone (sounded like a teenager) said "like 40 years old?"

That's not as bad, but still dumb

But what inspired me to make this post is some instagram comment saying "why would I wanna live forever, living until 40 is enough"

That's also not that bad, it's not directly implying that 40 is really old, so it passes
