On 15-2-24 Dr Karl said fish change from female to male by changing chromosomes from XX to XY. Actually, sex changing species (which I observed in my aquarium) are born with both male and female gonads, with hormones determining which mature and function. When the male dies, the testosterone rises in the dominant female causing the male gonads to mature and the female to atrophy. No change in the chromosomes. See https://earthsky.org/earth/how-can-some-fish-change-from-female-to-male/

About using tape to keep your mouth closed while sleeping (Jan 19). It's one of the Buteyko tricks to improve breathing. With mouth closed, CO2 in blood is higher so pH is more favourable to release O2 to the organs.
