Some people say that old people are the worst, meaning they are grumpy. Well that excuse should be replaced because according to a new study, middle-aged people are grumpy.

According to The Telegraph, researchers in Belgium discovered that people's satisfaction with life starts to drop as early as their late-20s and does not begin to recover until well past age 50.

It's as if the happiness curve is U-shaped. Young adults are carefree and full of hope for the future and the over 50 crowd have come to terms with the trials of life. And, in the middle, they're beat down and bummed out.

So don’t be bummed out, live like you’re forever young!
