Ultimate breathhold
William Trubridge has mastered breath. He is a world leading freediver (from Christchurch) and in this, one of my favourite TedX Talks, he takes us through the process of a freedive. He shows us what is possible, and yet, even simple breath exercises can give us more vitality and better physical and mental health. https://www.ted.com/talks/william_trubridge_this_is_why_i_free_dive_a_journey_into_the_deep
