Ok, the article itself doesn't actually give you much info:
Hugs Are Good for Your Heart
But I gotta say hugs are good, they're my favourite way of greeting friends and family, though with some it just ain't what they want/appreciate... But for me it's the best, you get to feel all warm and fuzzy inside, along with wanted and liked by those around you. And bonus by getting this feeling you give the other person the same in return, simply by returning the hug!
And it can just be a friendly hug (though the other type are good too, for a different reason), but there's something different about having a friend you feel comfortable enough to hug as opposed to just talk.. Though it's difficult to say how to cross that boundary..
So my advice today, go and hug someone close to you, they'll probably appreciate it. :-D
Here's a big virtual hug for you too.
