Sleep

Is insomnia really a problem of modern life... or is the struggle for sleep older than you think?

But Shakespeare's characters were up all night, sleepwalking, and freaking out about their daily lives. Just how have our sleeping patterns really changed since the invention of the electric light? Dessa dives deep into the science of sleep to find out what we need, what we're missing, and why it can be so hard to get a full night's rest.See omnystudio.com/listener for privacy information.

Why are we so judgemental about how others beautify themselves? Do you wear eyeliner? Dye your hair? Ever gone under a laser, needle, or knife?

From Instagram Face to pretty privilege, the male gaze to “anti-feminism”, cultural appropriation to the capitalist machine - a tour of the cosmetic cuts surprisingly deep.See omnystudio.com/listener for privacy information.

Why do we hate one another - and how can we stop? How and when does conflict metastasize into hatred?

Why do you love the way you do? We're expected to love only one romantic partner at a time. But we can love more than one parent, sibling, and friend - so why do so many cultures demand monogamy in romance? Is it time to reconsider the old model? Dessa speaks with a philosopher, an economist, and sexpert Dan Savage to talk about love, sex, and commitment.See omnystudio.com/listener for privacy information.

But in the popular imagination, big crowds are often associated with danger - with hysteria and violence.
