Twas the night before Christmas when all through our home, friends were waiting for drinks at the party we'd thrown.

With an espresso martini mixer from Fever Tree, all you need to add is the vodka, you see.

Five espresso martinis ready in a second. A Christmas miracle, everybody reckoned.

So this holiday season mix with the best,

with fever tree cocktails for you and your guests. Please enjoy responsibly.

Twins have long captured the public imagination. Movie plots, ad campaigns, viral videos of twin toddlers babbling at each other in what seems like a secret language. Something about twins grabs our attention every time.

But it's not only the general public that's fascinated with twins. Twins have also garnered their share of attention from psychologists

and other researchers because of what they can tell us about how our genes and environment interact to make us who we are.

Where is twin research today? As our understanding of human genetics has advanced in recent years, do twin studies remain vital?

What about twins who are raised apart and meet later in life? What can we learn from those

natural experiments? And why are so many people, scientists and lay people alike, so fascinated

with twins? Welcome to Speaking of Psychology, the flagship podcast of the American

Psychological Association that examines the links between psychological science and everyday life.

I'm Kim Mills.
