Nov 8 2021 - My Dog and Me

 

I have never wondered what the difference is between dog urine and human urine.  But somehow, people seem to ask this question  a lot as it comes up at the top of Google question/answers. Cuteness.com wants to answer this.  Millie was pleased as the site had videos of dogs running in their first snow fall.  Here's what they say:

The only difference between dog urine and human urine is that they come out of differing species.... Dog urine contains water, bacteria, ammonia, uric acid and dog hormones.  It's these hormones that are different from human urine.   Any dog nose can smell these hormones to know the sex, health and even the breed of the dog that urinated. When the dog urine dries, it does so in tiny crystals that can release their smelly messages when they are moistened again from humidity or being sniffed through a dog's wet nose. 

How did we get the expression 'pee' - that's the command I use for Millie when she is sent outside.  It is 18th century euphemistic use of the initial letter of piss. 


Shakespeare was  among the first to use the letter "P" to stand in for the word "piss," in Twelfth Night. The letter sound, written since at least 1880 as "pee," has been in use ever since.

And piss? This from the New Republic: "To piss derives ultimately from the Vulgar Latin verb pissiare. The proper Latin verb meaning to urinate was mingere, which gives us medical words like micturition. Via the medieval French verb pissier (12th century), to piss crops up in many medieval English texts, including Chaucer."

And if one wants to emphasize to Millie that she really is to go pee, then it is "go pee-pee".   This is considered a reduplicated form of pee.  And French and German have these versions, too - e.g. pipi in French.

And here's our joke on the topic:

When you really have to pee, you're Russian to the bathroom, when you walk out, you're Finnish, so what are you while you're inside? 
European!

Jan 29 2020 - Eyefull

I was at the Optometrist yesterday and I wondered about the eye. He told me that the human eye has the fastest metabolic rate in the human body because of the rate it is regenerating images.  I hadn't realized that seeing takes up 50% of the brain's functionality.

What about these facts? 
  • If the human eye were a digital camera it would have 576 megapixels.
  • We spend about 10% of our wake time with our eyes closed.
  • An ostrich’s eye is bigger than its brain.
  • Dolphins can sleep with one eye open.
  • Birds, cats and dogs have three eyelids.
  • Humans can see more shades of green than any other colour.
  • The world’s most common eye colour is brown.
  • The eye has over 2 million moving parts.
There are colours that are too complex for the human eye to comprehend. These are known as “impossible colours”, which cannot be perceived due to being outside the strength of our three types of cone cell in the retina. However, some of these colours can be seen by mixing colour signals from the two eyes, or by looking at special “fatigue templates”.  

When I looked at this picture of waterlilies at Longwood Gardens I was amazed at the how many flowers are in each cluster.
