New year's breathing exercise

Former Olympic swimmer, professional triathlete, and ultra endurance competitor Chris Hauth extends beyond physical training to emphasize mindset, strategy, and focus -- integrating both mindset and performance.
Hauth has coached everyone from military operators to executive teams, and conducted this brief breathing exercise on stage at our second annual a16z crypto Founders Summit in between sessions; and we are sharing it (virtually) here with you... as a breather for the new year!
