34 Best 40th Birthday Captions for Reaching a Major Milestone | Facetune (2024)

Gasp ... It's the big 4-0! You made it — congrats!

How does it feel? Well, actually, I know what you're going to say. “It feels old” — right?

The truth is, 40 is the new 30 these days.

Unlike the generation before us, everybody's buying houses, getting married, and starting families later in life. And this is good news because it means that there isn't as much pressure on us to settle down at a young age.

In other words, don't feel bad if you're not quite where you thought you'd be earlier in life.

Continue to enjoy your forties just as much as you enjoyed your thirties. And don't forget to welcome the milestone of 40 by posting photos or videos of your monumental celebration on Instagram.
