At school, Little Johnny’s classmate tells him that most adults are hiding at least one dark secret, so it’s very easy to blackmail them by saying, “I know the whole truth.” Little Johnny decides to go home and try it out. Johnny’s mother greets him at home, and he tells her, “I know the whole truth.” His mother quickly hands him $20 and says, “Just don’t tell your father.” Quite pleased, the boy waits for his father to get home from work, and greets him with, “I know the whole truth.” The father promptly hands him $40 and says, “Please don’t say a word to your mother.” Very pleased, the boy is on his way to school the next day when he sees the mailman at his front door. The boy greets him by saying, “I know the whole truth.” The mailman immediately drops the mail, opens his arms, and says, “Then come give your Daddy a great big hug!”#Joke

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
