What happened to the noble art of the manly cry?

It's interesting to me that last week I saw an article on HN that bascially asked the question "Is it ok for men to cry?" And now this article asking "What happened to the noble art of the manly cry?" It's interesting to me because I used to be a young man who didn't cry, and now I am older (late 50's) and I cry. I feel no shame at all and think it's a sign of sanity. What happened? Life happened. The older you get, the more things that make you want to cry happen. Speaking in general terms, parents pass away, you get divorced, you lose your house, you get fired or layed off, your best friend dies of a heart attack, your kid OD's on drugs; any number of things can and often do go wrong. I think Joe Biden is currently a great example of a man who cries. If I could send a message to my younger self I'd say go ahead and cry, because you will and you'll be better off for it.

Over the last century men in many parts of the world (but not all) have become substantially more restrained in how they convey emotion physically. Watch a hollywood film from the 30's and you'll see men hugging, slapping each other on the back, holding hands, walking arm-in-arm, etc. in a very casual manner. Man hugs still happen in movies, but only in times of extreme emotion. Think back to the last time a co-worker gave you a hug. It was probably quite a while ago!

Some cultures still show a lot of emotion and have a lot of physical contact (e.g. Turks). People in these cultures also tend to stand much closer when talking. Put a Western European or North American in their midst and he'll feel very uncomfortable. Showing strong emotions is also generally more acceptable in these cultures. I may have fist pumped a couple times when my team won the Stanley Cup, but I've seen Turks do cartwheels, flop on the ground in hysterics, get up and start hugging everyone in the room because their soccer team won a quarter-final!

So, what happened? Why, in less than a century, did we become so aloof and restrained? Homophobia may be one possible reason. If two men unconsciously stand too close to each other while looking at the same thing someone (a woman did this to me once) will exclaim "ARE YOU TWO GAY!??". Physical contact, sharing emotions, etc. are things that, in the last century, have become off-limits for heterosexual men, and women enforce this as much as men do despite the fact that the same standard does not apply to women.

The psychological effects of this on men are probably not good. It's something that we should honestly make an effort to reverse, but how do we do so? What are things going to be like in another century if we don't?

The article seems to be exhorting for more crying, but isn't it more likely that the Scandinavian / English / global business culture is spreading and will take over more and more of the world.

Maybe the "advantageous" solution is for more people to gain more control over their emotions and learn to mitigate the negative effects of fewer outward expressions. The article claims English speaking men have only learned to do this in the last few hundred years, but it seems to coincide with exponentially increasing size and power of that group.

Moreover, own little tech industry seems to be much less expressive than the industries that we are supplanting and replacing. And frankly, I think that lowered emotional availability is attractive to many of our most talented members and promotes their success.

According to the Isaacson biography, Steve Jobs used to cry in business meetings.

It's more likely that your declining testosterone is to blame.

edit: Please explain the downvotes, I'm trying to offer a more scientific explanation.
