I think that FB have good and bad points.
For example, thanks to FB, I was able to reconnect with my old school friends after 20 years of separation

So, we can't deny that FB really can help you to find some old friends but it's not healthy and wise to be on FB whole day, and don't go out, meet real friends, walk outside etc.
It's much better to meet real friends outside than virtual friends online
