REVEALED: This Is Why You're So Addicted To Facebook!
Guess what? You want Facebook "likes" just as much as you want to get married - or to have children.
A new study, carried out by Carnegie Mellon University, has revealed that a positive response to a new profile picture, status update or life event can give you a seriously significant boost in mood and self-esteem, similar to that of getting engaged or giving birth.
And that may explain why you can't quite bring yourself to put down your phone.
There's definitely a way to work this one to your advantage, though; while the positive consequences come about more from comments or personalised posts - rather than simply getting a like or reaction - one of the study's co-author's said that it really doesn't take much effort to make someone's day that little bit happier.
"We're not talking about anything that's particularly labour-intensive," Dr Moira Burke explained. "This can be a comment that's just a sentence or two long.
"The important thing is that someone such as a close friend takes the time to personalise it.
"The content may be uplifting, and the mere act of communication reminds recipients of the meaningful relationships in their lives.
"They're reminded of the people they care about in their lives."
So there you have it.
If you really can't quit Facebook, share the love around and sprinkle your loved ones' profiles with plenty of comments.
They'll <3 it.
