@steven: 1 in 3 middle-aged men have sleep apnoea and have no idea. And approximately 70–80% of people with clinical sleep apnoea go undiagnosed. It’s the kind of statistic that makes you realise how much can be happening inside our bodies without us knowing, which is why Dr Andy Galpin’s work is so useful. He helps make sense of the signals our bodies are giving us before they become impossible to ignore. Andy is a human performance scientist and professor who’s spent 20 years working with everyone from Olympic gold medallists to people who just want to wake up without back pain. But what I respect most about Andy is how focused he is on understanding what actually makes humans perform better, while still being willing to evolve his thinking as new research comes in. We broke down: - Why Andy has changed his thinking on grip strength and now believes muscle power may be a better marker of ageing. - The emerging research on muscle power and why it becomes critical as we age. - If deep sleep and REM metrics on your wearable might not be as useful as you think. - What Andy found in my own blood results that changed my supplements and daily routines. - Why taking longer rests between sets in the gym could actually improve your training. At the end of our conversation, I told Andy he is "a wonderful synthesiser of very, very complex things." There’s so much health advice coming at us right now - sleep scores, blood tests, longevity markers, wearables, training advice. Andy helped me understand which of those signals may deserve more of our attention. If you want to sleep better, train better and make more informed decisions about your health as you get older, this conversation is out now. Watch on YouTube, Spotify or Apple Podcasts.
