Does this sound like the set of challenges you might be facing?

• I’ve never even properly introduced myself to the neighbor across the hall or the coworker at the next desk
• I’ve noticed all my friends come from the same narrow slice of my life
• I want something I can do in the ten minutes right before I train that actually primes my body, so the opening stretch of the workout feels stronger instead of like I’m still shaking off the rust for the first twenty minutes.
• I want the benefits of altitude training without packing up and moving to a mountain
• I’ve already been building breath tolerance for weeks and the easy stuff feels too easy now

Practices that may help

1. The Oxygen Advantage, Made Practical
   The Oxygen Advantage is Patrick McKeown’s framework for improving athletic and cognitive performance by increasing CO2 tolerance and optimizing breathing mechanics through nasal breathing, breath holds, and simulated altitude training. The underlying physiology (Bohr effect, CO2 chemosensitivity) is well established; specific protocol outcomes in trained athletes have promising but limited RCT support.
2. Invest in the people physically nearest you
   Your immediate neighbors, officemates, and classmates are your highest-ROI friendship investments — propinquity is already working.
   The Propinquity Effect (Leon Festinger)
3. Counteract propinquity bias in friend selection
   Proximity is a powerful friendship filter — but it is not the same as fit.
   The Propinquity Effect (Leon Festinger)
4. Simulated altitude breathing drills before training
   A 10-minute pre-workout hypoxic breathing sequence primes the oxygen-delivery system before exercise begins.

5. Breath-hold walk — simulate altitude during exercise
   Hold your breath after an exhale while walking to build CO2 tolerance and trigger mild hypoxic adaptation.

6. Advanced breath holds — MHT (max hold training)
   Build CO2 and O2 tolerance with progressive maximum breath holds — used by elite freedivers and now applied to sport.

7. Cultivating friendships of virtue over pleasure or utility
   Invest most deeply in friendships where mutual character development — not just enjoyment or usefulness — is the bond.

8. Design your daily environment to create repeated exposure
   You cannot become friends with people you never run into — engineer the run-ins.
   The Propinquity Effect (Leon Festinger)
9. Treating friendship as the most essential pleasure
   Invest in the quality of a small number of close friendships as your primary wellbeing strategy.

10. The Propinquity Effect (Leon Festinger)
    The propinquity effect, documented by Leon Festinger's classic apartment studies, is the finding that physical proximity — living near someone, sitting next to them in class, working on the same floor — is one of the strongest predictors of friendship formation. Proximity drives repeated exposure, which builds familiarity, which is interpreted by the brain as safety and liking. The implication is that the architecture of your daily life shapes your friendships far more than active choice does.
