    I'm sorry but this woman Malia does absolutely nothing for me. Other then to be a friend to Leora, I don't know what she is doing here. She has those terrible inverted nipples that I find a total turn off. This is my own personal opinion and do not expect others to agree with me.

    And you have that terrible inverted attitude where anything not to your liking is bad.  All people are different, enjoy the differences.

  2. Urine-indicator dye is a substance which is supposed to be able to react with urine to form a colored cloud in a swimming pool or hot tub, thus indicating the location of people who are urinating while they are in the water.[1] A 2015 report from the National Swimming Pool Foundation called this "the most common pool myth of all time", with nearly half of Americans surveyed by researchers believing that the dye existed.[2]

    Urine is difficult to detect as many of the naturally occurring compounds within urine are unstable and react freely with common disinfectants like chlorine, creating a large number of disinfection by-product (DBP) compounds from the original organic chemicals in urine.[3]

    In an article published in 2000, Snopes confirmed such a dye did not exist.[1] However a study published by the University of Alberta in 2017 identified urine in hot tubs and swimming pools based on other markers such as acesulfame potassium, used extensively as an artificial sweetener, being passed chemically unchanged in urine, and not suffering from DBP-related changes in water.[3]

    Rumours of the origin of urine indicator-dye go back at least as far as 1958,[1] and the story is commonly told to children by parents who do not wish them to urinate in the pool.[2] A 1985 biography of Orson Welles describes him using such a dye as part of a prank in 1937.[1]
