00:00Imagine being frozen solid.
00:03Your heart is a block of ice.
00:06Your blood is stopped.
00:08You aren't dead, but you aren't alive.
00:12Here is the body horror of the cold.
00:15Ice is a cellular assassin.
00:18When water freezes, it expands into jagged glass shards, shredding your cell membranes
00:25into microscopic confetti.
00:27For almost every living thing, the first frost is a death sentence.
00:33But meet the biological sorcerer.
00:37The wood frog has mastered a miracle called cryoprotection.
00:41The moment it feels the frost, its liver floods its body with massive doses of glucose.
00:49It turns its blood into a thick, sugary syrup.
00:53This syrup prevents ice crystals from ever forming.
00:56Its organs don't shred.
00:59They enter a glass-like state of suspended animation.
01:03It isn't fighting the cold.
01:05It has become the cold.
01:08Six months without a heartbeat, nature's ghost just came back to life.
01:14And the body of the cold.
01:15This was a blowout for the cold.
01:15There's a cold out of the cold.
01:16You can see the cold out of the cold.
