People who hold a positive attitude toward ageing live longer and are less likely to develop dementia, according to more recent research cited by Castel.

Huberman reflects on how experiencing highs and lows at scale recalibrates the emotional baseline — things simply not sucking becomes a deeply savourable state rather than a disappointment. Castel ties this to the positivity bias: as we age, we increasingly allocate attention and memory to positive information and away from negative, both for mood regulation and perhaps cognitive efficiency. Older adults who've lived through the Holocaust, Castel notes with genuine awe, often present as among the most joyful people he's met — not because they've forgotten, but because they've integrated. He then makes a case for structural intergenerational mixing, citing the Senior Scholars Program at UCLA in which older adults audit undergraduate courses. In his psychology of aging class, two older therapists sitting in the room provided richer case material than any textbook, and students consistently rated them as the most valuable part of the course — not the professor.
Castel's framework for aging well comes down to three letters: Attitude (a positive yet friction-embracing outlook on what you can control), Balance (physical and mental, not extremism), and Connection (quality social relationships that shrink in number but deepen with age). Together, these predict longevity and cognitive health better than any single biohack.
Castel distills the keys to successful aging into three principles — Attitude (positive outlook), Balance (physical and mental), and Connection (social relationships) — drawing on research and interviews with older adults.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
