In the ‘90s, most of the world’s medicines were manufactured in the United States, Europe and Japan. Today, almost 80% of them come from China. In her book, “China Rx: Exposing The Risks Of America’s Dependence On China For Medicine,” Rosemary Gibson says that China is becoming the world’s pharmacy, but that development, she argues, comes with many risks.

First: ‘Tis the season for giving and sharing… and holiday shopping. Whether it’s toys, clothes, books, or electronics, chances are that most of these items were manufactured in factories. Joshua Freeman walks us through the history of factories, and how they continue to shape our modern world.

Next: Do you ever find yourself flipping through photo albums and feeling nostalgic for old times? Well, according to Krystine Batcho, longing for the past can shape how we think about the present. And in some case, it can be beneficial.

Finally: In the era of fake news and sensationalist media, public trust in local and national news outlets is waning. But libraries are increasingly coming to the rescue and in the process are steadily reshaping the face of journalism.

First, in the late 1950s, Berry Gordy Jr. - who had worked for Ford Motor Company, been a boxer, and owned a record store - had a vision. He wanted to introduce the world to a new sound: the sound of Motown. And with every hit he produced, Gordy slowly but surely began to transform American culture.

Then, we know that the heart is a symbol of love and emotion. But for doctors, of course, the heart is a sensitive and vital organ that affects the entire body. Cardiologist and author Sandeep Jauhar argues that the health of our hearts depends not just on things like cholesterol and blood pressure but also on psychosocial factors - including friendship, affection, and community.

Shortly after Michael Jackson died in 2009, Helen Brown, a music critic for the Daily Telegraph wrote that the Jackson 5’s 1969 single “I Want You Back,”  is “certainly the fastest man-made route to pure joy.” And while Michael, Tito, Jermaine, Marlon, and Jackie may have stolen the spotlight, the group - like so many others - emerged from a hit factory created by a man named Berry Gordy Jr.

Gordy founded Motown after stints as a boxer and as a worker in a Lincoln-Mercury plant. And he quickly turned the label into a force to be reckoned with, drawing on a formula of quality control he had learned at the auto factory, taking raw talent like Diana Ross and Smokey Robinson, and refining them into international stars. As a result, Motown became one of the most successful black-owned music companies in American history.

We talk to music journalist Adam White, author of  “Motown: The Sound of Young America,” about Gordy’s meteoric rise and his lasting legacy.

The Grinch’s is two sizes too small. All Green wants to know how you can mend a broken one. You can destroy them, steal them, break them. They can pine or ache or wander. Suffice it to say, hearts are a big part of our culture. After all, though our kidneys are vital, there aren’t many pop songs about them. Still, as important as they are to our culture, our hearts are even more important to our health. Heart disease is the leading cause of death in the United States, and chances are that you know someone who has been affected by heart issues. Dr. Sandeep Jauhar, the director of the Heart Failure Program at Long Island Jewish Medical Center and author of “Heart: A History,” takes a look at how we address heart health, and how we could do better.

First: in the early 1970s, the average age of first-time moms was 21. Now, the average is 26. We talk with economist Caitlin Knowles Myers and New York Times correspondent Claire Cain Miller about why so many couples are putting off having kids and we also consider how education, politics and geography intersect with that decision.

Next, dear listeners, you had some thoughts about our show regarding the future of work. We’ve highlighted some of your workplace experiences with technology. Both the good and the bad.** **

Then: what if a personality test dictated the course of your career? For many, over the past several decades, the Myers-Briggs did just that. And it opened the door for personality testing in corporate America, the military, and even the church.

The American family is changing in many different ways. But one of the most important is that, on average, American women are giving birth later. And birth rates have hit a 30-year low. In the early 1970s, the average age of first-time moms was 21… it’s now 26. The same trend is impacting fathers - their age has gone from 27 to 31 over the same time period. But why did this change happen? And what does it mean for our society, our economy, and our families? To find out, we talked to Caitlin Knowles Myers, an economist at Middlebury College who’s studied female fertility, and Claire Cain Miller, a correspondent for The New York Times who’s written extensively about the topic.

If you were asked to describe your personality, you might choose words such as “funny” and “outgoing,” or “shy” and “quiet.” But what if those were not quite the right words? The Myers-Briggs - which many of us have taken - promises to assess your personality, and assign you a specific “type.” In her book, “The Personality Brokers: The Strange History of Myers-Briggs and the birth of Personality Testing” Merve Emre examines the Myers-Briggs Type Indicator (which is its full name), and how it has transformed the way we think about ourselves and those around us.

First, small businesses are the backbone of America. Or are they? Economist Robert Atkinson wants you to hold your horses and think again. He says we often favor small businesses and villainize large corporations, despite the fact that being big may enable companies to potentially contribute more to diversity, fair wages, and more generous employee benefits.

Next, many of us may have a bit of a precision fetish, according to author Simon Winchester. Consider car commercials or watches that tout precision engineering. But how did we get to a place where precision has become so important? Winchester notes that it goes all the way back to the 18th century. And without precision engineering - without replaceable batteries and reliable mass production - our lives would be very, very different.

Then, you and your best friends have more in common than you probably think. In fact, it’s likely your brain and your friend’s brain react in really similar ways to certain prompts. UCLA’s Carolyn Parkinson compared brain activity among friends and acquaintances and found that buddies are bound by more than social surroundings. And heads up, our genes determine our friendships, too.

First, swing states have a ton of power in determining control of Congress and many of the people living in those states have experienced the effects of automation in the workplace. Author Brian Alexander explains how technological progress has created fear, uncertainty, and shattered communities in swing states including Ohio.

But it isn’t entirely fair to blame technology for *all *of our problems, including the challenges created by the gig economy. Historian Louis Hyman says temp work in America existed long before Uber and TaskRabbit.

What do the people making robots or dreaming up new tech policy think of Americans’ conflicted feelings about what technological advances have meant for our economy? It’s complicated, but they say including more workers in conversations about new tech is crucial.
