"Thank you for putting together this online learning platform for people like me, especially during this unusual time in our world. I am very new to surfing and have had some bad experiences in the waves gasping for air. I wish I would have had your teachings before trying surfing. Especially, STAY CALM and ENERGY SMART. I have thoroughly enjoyed learning through your online program and understanding more about CO2 tolerance.My whole life, I have thought that the length of holding my breath was based on my need for oxygen, not my tolerance to CO2. I am learning so much and look forward to learning more. Thank you for everything Augusto!"
