Let It Pee
Sunday
Urine is yellow because of urobilin, an enzyme which derives from old blood cells that your body has broken down to be flushed out as waste.
Monday
Scientists at the Georgia Institute of Technology discovered a “new golden rule”; that all mammals over 3 kilograms in weight take about 21 seconds to empty their bladder. Larger mammals like elephants certainly hold more urine, but also have larger urethras to drain it faster, with the same final pee time.
Tuesday
For years it was believed that healthy urine was a sterile liquid, but this myth was busted by research in 2014 by researchers finding bacteria in the urine of otherwise healthy women. Earlier tests may have simply not been sensitive enough to detect urinary bacteria.
Wednesday
The unique urine smell many people detect after eating asparagus comes from aspargusic acid, which is found nowhere else in the food world. The body breaks this unique acid down into sulfur compounds, which quickly evaporate when excreted, hence the unique smell.
Thursday
Even if you’re really thirsty, drinking urine is a bad idea. Though it is 95% water, pee also contains toxins and metabolic products your body wants to flush out. Worse, because of the salt content, it can make you more dehydrated than when you started, as with drinking seawater.
Friday
The average human bladder holds about 2 cups of urine, but you’ll feel the need to pee when it’s about half full. Holding it is not an instinct, but a learned skill, which babies and toddlers haven’t acquired yet.
Saturday
Public urination is a crime in every US state, and in many countries carries heavy maximum fines and even possible jail time.
