We're off this week for the Memorial Day Holiday in the US so we present here one of our most popular episodes, a classic IF from August 13, 2021 with the incomparable marine biologist from Australia, Dr. Vanessa Pirotta. Take a deep breath and enjoy this deep dive!

WHALES spend their entire lives inside a medium, water, in which they can’t actually breathe. So throughout the day, and the night, they have to swim to the surface to take a breath of that sweet, sweet ocean air… or they die! We humans, and other land lubber mammals like us, are spoiled, just inhale, anytime you want, and… problem solved. But —

What The IF humans had to breathe by dunking our head in water?

The amazing Dr. Vanessa Pirotta joins us from Sydney, Australia to take us into the wet and wild thought experiment, so we can learn real science!

Imagine living the life of the whale, turned on it’s head. What world would we have built if our bodies worked this way? It’s like what if we emerged from the oceans, as we believe life did, but never adapted to breathing outside the water like we used to. Humans with gills? Are we wearing helmets on our head that are filled with water? Do we fill our *buildings* with water? Water the IF!
