Iโm working my way through the Breath Hold Mastery course, and I can only concur with @Edward Brittains comments.The more I learn about breath holding, and breathing in general, I see how little I actually know and a whole new way of living and breathing unfolds itself for me. Fortunately, there is some repetition of earlier knowledge, so it roots better in my mind, and there are so many โOh, thatโs why this happensโ experiences. I love Stigs passion and his scientifically sound, and sensible, advice. I can hardly wait for tomorrow, and the next days, morning exercises so I can use more of his training suggestions. Donโt tell my wife, but I think Iโm a little in love. ๐ฅฐ ๐ซ๐๐ซ๐ง
