You order some stuff on the Internet and it shows up three hours later. How could all the things that need to happen to make that happen happen so fast?

In this episode, we break the thermometer watch the mercury spill out as we discover temperature is far stranger than it seems. Five stories that run the gamut from snakes to stars. We start out underwater, with a snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Farenheight is a sound marker of health.

This episode was reported by Lulu Miller and Molly Webster and was produced by Lulu Miller, Molly Webster, and Becca Bressler.

Today, Lulu and Latif talk about some of their favorite episodes from Radiolab’s past that hold new power today.

Lulu points to an episode from 2008:

Imagine that you're a composer. Imagine getting the commission to write a song that will allow family members to face the death of a loved one. Well, composer David Lang had to do just that when a hospital in Garches, France, asked him to write music for their morgue, or 'Salle Des Departs.' What do you do? This piece was produced by Jocelyn Gonzales.

And Latif talks about an episode Jad made in 2009. Here’s how we described it back then:

Jad--a brand new father--wonders what's going on inside the head of his baby Amil.

(And don't worry, you don't need kids to enjoy this podcast.) The questions here are big: what is it like to be so brand new to the world? None of us have memories from this time, so how could we possibly ever know? Is it just chaos? Or, is there something more, some understanding from the very beginning? Jad found a development psychologist named Charles Fernyhough to explore some of his questions.
