Why do we often feel drowsy after eating a big meal?   You may be happy to know that there actually is a scientific reason for this. Feel free to print this out and show it to your boss when you're proposing to implement "nap time" after lunch.
After we stuff ourselves, blood converges on the digestive system and internal organs. Since there's only so much of the red stuff to go around, that means less blood is supplied for other activities. Also important are the chemicals your food breaks down into when it's digested.
Amino acids can induce sleep, while serotonins constrict blood vessels, contributing to drowsiness. Alcohol may also cause sleepiness, and carrying those big plates of food at the all-you-can-eat super buffet will definitely tire you out too.    (Source: WHEN DID WILD POODLES ROAM THE EARTH?

The first known heart medicine was discovered in an English garden. In 1799, physician John Ferriar noted the effect of dried leaves of the common foxglove plant, digitalis purpurea, on heart action. Still used in heart medications, digitalis slows the pulse and increases the force of heart contractions and the amount of blood pumped per heartbeat.

Where does the phrase "once in a blue moon" come from?
The phrase does not refer to color.  There once was a "blue" moon - when the Krakatoa volcano in Sumatra erupted in 1883, sending particulate matter into the atmosphere and making the moon appear blue. This expression refers to the times when a full moon occurs twice in a month. It occurred most recently on January 31, 1999. Another blue moon
will be arrive on the night of March 31.  Two blue moons in one year happens every 20 to 40 years with the last occurrence in 1961. Astronomers predict the next occurrence of two blue moons in one year will be in 2018, on Jan. 31 and March 31, and again on
the same dates in 2037.

When was the first Valentine's day celebrated?
The lover's holiday has its beginnings in the 4th century B.C. in Rome. The Romans held an annual lottery wherein young men would draw a young woman's name from a box. The couple would be assigned to each other the entire year for entertainment and pleasure. This celebration, traditionally held on February 15, also included banquets, dancing and foot races run in the nude.
Around A.D. 496, early church fathers sought an end to the pagan practice, but knew better than to upset the citizens by removing the lottery completely. Instead, they had
teenagers pull the names of saints from the box. The teen was supposed to spend the year emulating that saint's life as much as possible, which was probably not as much fun as
naked marathons. St. Valentine was chosen as the patron saint of the new event, and young Roman men resorted to courting females by sending handwritten notes delivered on February 14.  PANATI'S EXTRAORDINARY ORIGINS OF EVERYDAY THINGS By Charles Panati
