aging

"I'm This Old" is a brand new Twitter meme that really has people confronted with their age, and that's the scariest thought of all. 

If you remember all or most of these things then you're likely a sad Millennial who's feeling a little panicked yourself about getting older (we're totally not projecting here or anything...). Worry not, because you're not the only one going through the harrowing process of feeling like you don't fit in with the kids anymore. Pretty soon you're going to look at a group of 20-year-olds and be tempted to say "how do you do, fellow kids?"

In a way, we all sort of choose when we enter adulthood - and how. You can either choose to party and bullsh*t all the way through your twenties and thirties, or you can settle for a more reclusive, introverted path. These memes cover the latter.

If you've been on the internet over the past week then you've probably heard about the "how hard did aging hit you challenge," in which people on social media compare photos of themselves from 2009 with a current photo from 2019. The challenge started on Facebook and quickly gained popularity on other platforms, also inspiring some people to make satirical then-and-now posts.
