  • Question!

    I have a question for Dr. Karl, hopefully you can get to it sometime soon :D

    Why when we don’t need to go to the loo and then we drink a bit of water we need to go? Are we absorbing the water that quickly or are we tricking our brains? Thanks in advance, love the show to bits!

Talking Points

Recent interactions between the hosts and their guests.

Frozen vs fresh veggies, soap suds and nangs
Q: Is it possible to have too much muscle?
You can have too much muscle if it interferes with flexibility, but generally maintaining a healthy amount of muscle is beneficial for overall health.
Frozen vs fresh veggies, soap suds and nangs
Q: Why does some music evoke such strong emotional responses?
Certain music can trigger hormone release that affects emotional responses, causing feelings of nostalgia or even tears, linked to dynamic changes and the context in which the music is experienced.
Pollen peaks, jump scares and alcohol vs mood
Q: I'm wondering if the loud calls of tree frogs are caused by the metal pots they gather in, as they seem much louder. Is this to attract mates?
The loudness of frog calls can indeed be influenced by their environment. If they prefer metal pots for their resonance, it may be more effective for attracting mates, but further documentation is needed to confirm this hypothesis.
Pollen peaks, jump scares and alcohol vs mood
Q: I've noticed that sometimes when I'm in a better mood, the alcohol seems to affect me much stronger and much quicker. Why is that?
A person's mood can influence how they metabolize and react to alcohol. When in a better mood, the alcohol may have an enhanced effect due to the body's overall state, including hormonal levels and psychological expectations about intoxication.
Pollen peaks, jump scares and alcohol vs mood
Q: So my question is, if ants were bigger, would they become the dominant species across the world?
Ants have a complex social structure and a high power to weight ratio, which allows them to thrive at their current size. If they were larger, they would lose this advantage and face significant challenges in maintaining their colonies and ecological roles. Thus, they are unlikely to dominate at larger sizes.
