Please feel free to share your stories of how certain little self-care rituals changed your life for the better and have made you proud you started doing them.
You don't have to do all that stupid breathing nonsense - just do O2 and CO2 dive tables. You'll increase CO2 sensitivity without all the faffing about hyperventilating and its much safer since you're progressively increasing your tolerance and not jumping into doing dump shit like max-holds after hyperventilating, which is EXTREMELY dangerous.
