Miscellaneous

Here’s a bunch of things I’ve been working on that are unrelated to mental maths:

🧘 Science of Breathwork and Cold Fitness

Breathing exercises and cold training have so many uses and benefits that I didn’t believe them at first! These include the immune system, physical endurance, and altitude acclimatization.

I spent a bunch of time figuring out the science behind these so it will be easier to understand. My “Biology of Breathing” article has been read 100,000+ times since 2018 and has been influential in improving understanding of the Wim Hof Method amongst practitioners.

• Wim Hof Method – Biology of Breathing


• Science of Cold Showers and Ice Baths


• Ice Bath Calculator


• The 4-7-8 Breathing Technique for Sleep


• Should I take a Cold Shower after a Workout?


• Memory Techniques for Mindfulness Meditation

I also recommend the 2nd Intelligence program developed by Catherine McCarthy, using breathwork and meditation as tools to help you during your day (especially for professionals working in high-pressure environments!) I’m not affiliated with the program but it’s exactly the way I think breathwork and meditation should be used. Look here for the 2nd Intelligence app. It might even be still running a free 7-day trial.

🎸 Piano Arrangements of Metal Music

Ever wondered what dramatic metal music would sound like it it were written for piano? Okay probably not… But I was curious, and created piano arrangements to a few of my favourite metal tracks 🤘 (Full list)

• Piano version of Lordi’s “Hard Rock Hallelujah”


• Black Metal piano version of Mercenary’s “Lost Reality”
