Since September began, the sunlight seems to have softened a little, making it easier to spend time outdoors again.

This time, Jesse brings up the idea that exposure to sunlight causes the body to produce vitamin D — and puts a question to Peter.

What exactly happens in the body, and through what mechanism? And what can happen when vitamin D levels become too high or too low?

After listening to Peter carefully explain these related topics, Jesse seems to come up with a “good idea” of her own...

Not many days have passed since 2026 began,

and yet some of you may already be feeling a little worn out.

Peter, too, finds himself among those who feel “a bit exhausted,” and begins to speak about wanting to take a trip to refresh his mind.

As the conversation unfolds, Peter and Jesse share the kinds of travel plans they each dream of—

and before long, the topic expands into their personal “travel philosophies.”

So what kind of policies guide the journeys they imagine?

And what sort of trips are they truly envisioning?

Beloved by children all over the world, Santa Claus is someone many eagerly wait for as December approaches.

Though he is globally famous, the details of his work remain shrouded in mystery.

His job feels almost magical—sometimes even too unreal—
and as children grow older, some begin to question whether he truly exists.

But deep down, everyone knows the truth: Santa Claus is real.

Peter and Jesse, too, seem determined to prove his existence without a shred of logical doubt,
and have decided to shine a spotlight on the hidden mechanics behind the “miracle of one night.”

What emerges, however, is a series of feats that appear scientifically impossible…

So—can Peter and Jesse really prove that Santa Claus exists?

For those who want to believe in Santa Claus through science,
we present this video to you.
