- Nutrition affects cognition
- Sleep is foundational
- Technology tools available
- Individual optimization needed
Key Moments
Balance board at standing desk for proprioceptive training
Brennan discusses using a balance board on his standing desk all day for proprioceptive feedback and graviception training, describing how different types of balance boards (half ball, roller, cone) offer varying challenge levels.
"I'm constantly getting that proprioceptive feedback. So you're always on a balance board at work when you're standing? Yeah."
Sleeping on an inclined bed for glymphatic flow
Asprey describes his inclined bed setup and the theory that slight head elevation improves cerebrospinal fluid flow during sleep. The guest discusses the gravitational effects on acid reflux and glymphatic drainage during sleep.
"So, what are the pros and cons of sleeping on a flat bed versus a slightly inclined bed?"
Dead hangs and rucking as gravity resistance tools
The guest recommends dead hangs, rucking with weighted backpacks, balance boards, and float tanks as practical ways to manage one's relationship with gravity for health and longevity.
"Balance boards. You know, in the book, I talk about a whole bunch of different ways you can fight gravity, whether it's dead hangs, which is a very helpful way."
Float tanks alter perception of time through gravity removal
Discussion of float tank therapy and how removing gravity's force on the body can affect perception of time and induce flow states, supported by functional MRI studies showing brain changes after flotation.
"it shows, we've been able to see that it can actually affect the perception of time itself when you no longer have the force of gravity working on your body. It leads to a flow state"
