Where did this myth that our frontal lobe develops at 25 actually come from? What does the death penalty and Leonardo DiCaprio have in common? You've probably seen TikToks, videos, tweets, memes, but what is the truth about brain maturity? That is what we're breaking down today, including: 
Why brain development is a lot more complicated than a number
The specific role of the frontal lobe 
The early 2000s research that defined how we see brain development 
Why our brain actually develops in spurts 
The good news for 20 somethings

411. Growing up online, early fame and rediscovering your creativity ft. Arden Rose

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/369da92f-23b7-4adf-a883-b439007f14de/transcript

Why does it suddenly feel like everyone has a diagnosis? From ADHD and autism to anxiety, trauma, burnout, and depression - mental health language is everywhere right now. But are rates actually rising? Or are more people finally being seen after years of being overlooked, misread, or excluded from the stereotype? In this episode, we unpack the psychology, politics, and culture of diagnosis: how diagnostic criteria have changed, why context matters, what social media has done to this conversation, and the tension between labels as affirming, or oversimplified.

We explore:
•        What the data actually says about rising diagnosis rates
•        Why historically missed groups are being recognised more now
•        The role of context in shaping our experiences
•        The risk of pathologising ordinary human struggle
•        When scepticism is useful - and why it should be aimed at systems, not individuals
•        Why a label can still be meaningful, helpful, and nobody else’s business

410. Why does everyone have a diagnosis these days?

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/d1949fd2-7c27-4f92-bf8f-b439007673ca/transcript

It can feel like the world - and our future - has never been more precarious or frightening. It’s a very normal response to feel anxious about it - and in many ways, being concerned is just a sign that you’re alive, switched on, and care about the what’s going on around you. But what happens when this anxiety becomes overwhelming, and we’re consumed by worry about the future? In this episode, we unpack:

• Why we’re prone to anticipatory anxiety in our 20s
• The evolutionary reasons for catastrophic thinking 
• Why long-term anxiety rewires our brain 
• When it’s healthy - and not healthy - to worry 
• How to rebrand anxiety as excitement
