Can smiling increase your happiness?

Smiling is my favorite thing!
Yes, three separate studies dating back as far as 1987 indicate that the physical act of smiling can have a psychological impact on how you feel.

Studies at the University of Michigan, University of Kansas, and an independent clinical study arrived at similar conclusions using three different methodologies.

In the most comprehensive study at the University of Kansas in 2012, 169 people were assigned one of three different facial expressions; a neutral expression, a typical mild smile, or an extreme smile lifting the cheeks known as a Duchenne smile. Then researchers used chopsticks to physically hold the expression in place. Participants were then asked to do a series of multitasking tasks, some of them quite stressful.

When asked about their mood and emotional state, the participants forced to smile were dramatically less stressed and happier.

It's quite possible that the physical act of smiling, as well as the extremes to which you smile, can have a psychological effect on your mood and your ability to manage stressful tasks.

Some of them are certainly more difficult than others, and many of them are hard to find gift worthy in the modern age.
Therefore, I offer you a modern take on anniversary gifts. How many of these will become traditional?
First Anniversary – The Ramen Noodle anniversary. Let’s face it, you blew $30,000 on the wedding, and your student loan debt hasn’t gone anywhere. Share a Cup O’ Noodles. Eat with chopsticks on the floor because you can’t yet afford a couch.
Second Anniversary – The Puppy Anniversary. She’s been looking at you with those eyes that say she wants to start a family, but you just bought a new couch. Get her a puppy instead.
Third Anniversary – The Kinky Lingerie Anniversary. Leather, silk or lace can re-fire the engines after a year of flannel pajamas that smell like the puppy,…

Donald Trump Hates Freedom of the Press, But Why?

Donald J Trump is challenging the concept of free press. He has publicly ridiculed ABC, CBS, NBC, CNN, BBC, the New York Times, the Washington Post, MSNBC, and many other news organizations. Some have called out his twitter rants as being distinctly fascist.
This past week on Meet the Press, John McCain, a Republican member of the U.S. Senate, while not mentioning Donald Trump specifically, called suppression of the press "how dictators get started". Freedom of the Press in the Constitution
Freedom of the Press isn't a new concept. Our founding fathers put it into the original Bill of Rights. Even in the 1789 they realized that a free press was essential for maintaining checks and balances to the power of government.
