Huggers Are Happier

I've never been much of a "hugger".  I'm definitely a man who likes his personal space, but this report on hugs has me thinking I should reexamine my position.

The report basically says that after studying a group of people, they determined that hugs not only made people have a better day, but that the effects of the hug actually carried over into the next day.  The report itself didn't mean much to me, but it did make me think about the people I've encountered who always want to hug.  As I was picturing these serial huggers in my mind's eye, I noticed a commonality...all of them are always smiling.  I'm sure you know one of these types of people, so is it the same for you?
