Here is the EXACT age you will be the most miserable in life!

A new study out of Dartmouth College in New Hampshire looked at data from almost eight million people over the past three decades to figure out when people are the most MISERABLE.

And the answer is . . . when you're 47.2 years old.

The study suggests, our happiness as adults goes in a U-shaped curve. We're happy when we're 18 (yikes really?)

.... then we start getting more and more miserable over our 20s, 30s, and 40s. It bottoms out when we're 47.2 . . . and then we start getting happier again.

So middle age is the worst? Isn't this supposed to be the time when we have it all figured out? ... or when we're close to figuring it all out ... or "finally know ourselves"?

The researchers say it's because you realize your big dreams really AREN'T going to come true. Wow. Harsh. Sorry.

There is some good news though!! As you get older, you start to put your life in a better perspective and you become grateful for what you have, which is why you start getting happier again.

In fact, researchers say, by the time you hit 70, you're just as happy as you were when you were 18. Great! So when we're almost dead? Sheesh.
