Full transcript

Breathe through your nose by default — walking, low-intensity cardio, desk work, sleep. Switch to your mouth only when the work actually demands it. It improves CO2 tolerance, sleep quality and dental health. Mouth tape at night only if a clinician clears you, and skip the rule entirely if your nose is obstructed or you have sleep apnoea. agegen.ai. Generate your prime age! ~~ Mr. Age
