Podbit · The Diary Of A CEO with Steven Bartlett
Adverse Childhood Experiences (ACEs) are directly visible on brain scans: higher ACE scores mean greater activation of the limbic system and the anterior cingulate gyrus, trapping people in a state of hypervigilance. A score of 6 or more cuts life expectancy by 20 years.

Steven Bartlett asks whether trauma can be seen on a brain scan, and Amen's answer is an unequivocal yes. His world's largest childhood trauma study — based on 21,000 subjects — showed a clear gradient: the more Adverse Childhood Experiences (ACEs) a person had, the greater the activation of their limbic structures, particularly the anterior cingulate gyrus, the brain's 'gear shifter.' [1] — Dr. Daniel Amen "ACE score 6+ = 20 years shorter lifespan: People with an ACE (Adverse Childhood Experiences) score of 6 or more die approximately 20 years …" 41:24 For trauma survivors, this structure becomes hyperactive, locking them in a cycle of worry and threat anticipation — the past is always in front of them rather than behind. Amen shares that his own wife is an 8 on the ACE scale and their adopted nieces are 9s, giving his research an intensely personal dimension. An ACE score of 4 or more raises the risk of 7 of the top 10 causes of death; a score of 6 or more cuts life expectancy by 20 years. For those without access to therapy or brain scans, Amen offers a practical toolkit: prioritise sleep, exercise, and nutrition; supplement with a multivitamin, optimise vitamin D (especially for darker-skinned individuals who need 5x more sun exposure), and add omega-3 fatty acids. Most of the 50 consecutive patients measured in one Amen Clinics study were suboptimal in omega-3. These are the foundations before anything else.
People with an ACE (Adverse Childhood Experiences) score of 6 or more die approximately 20 years earlier than the general population.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
