It is a 5 things day today - our pictures are abstractions from some metal pieces found a few weeks ago at a metal shop in St. Catharines. At the time I seemed to have organized the image into a focus on fives as much as possible.
Today's headline says that there are five events to watch today at the Rio Olympics. So I guess there is a natural orientation to things that come in fives. We seem to relate to things that come in fives - here are examples:
"Some things that come in groups of five are basketball positions, fingers and toes, food groups, the Great Lakes, oceans, senses, U.S. military branches and vowels in English. People that come in groups of five include the Marx brothers and the Spice Girls."
Another site:
"A perfect fifth in music, the five Olympic rings and the five elements are all things that come in fives. In mathematics, things are often counted in ones or fives because of the ease of multiplying, dividing, subtracting or adding within ones or fives (5, 10, 15, 20, 25)."
You might want to see the ranking of 'things that come in fives'. This is a big list and covers people like quintuplets and famous quintets.
