"
In general I think Americans -- especially men -- are very isolated from one another, especially as they age. This is both physical and emotional isolation."
I partially agree with this statement, but only for men. They are very isolated from one another emotionally.
They don't seem to have the ability to talk about their emotions with other men, and the other men don't know how to handle conversations like this. So they just don't talk. Most men feel more comfortable talking to women who they feel will understand, even then not always. Many men, sadly, talk to no one about their emotions.
They also are not comfortable being physical with each other unless it's to play some sport.
Women on the other hand talk about their emotions with each other all the time. They hug and have no problem kissing or holding each other. So they are not emotionally or physically isolated. Far from it.
My best friend and I cuddled on the couch the other night watching a movie.
I have no idea whether this is just an American thing with men but I do agree...in general.
There are always exceptions.
