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.

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.

Cheese affects my dreams also, as do any of the foods that I have food intolerance to, resulting in vivid, wild dreams, often nightmares. Cheese and other fermented foods contain amines which can adversely affect some people, including other symptoms like headache and diarrhoea. I would recommend keeping a record of any other symptoms your may experience when you have nightmares and, if they are troublesome, see an allergy specialist with expertise in food intolerances (eg. Royal Prince Alfred Hospital allergy unit). Some people may also have intolerances to colourings, flavourings, preservatives, aspirin and natural salicylates, yeast, wheat, milk or eggs.
