How to outrun a bear, crocodile & other rules of thumb

Sharing with you more useful and interesting Rules of Thumb from Tom Parker’s book “Rules of Thumb: Brilliant Guestimates, Shortcuts, and a few Shots in the Dark”.
I grouped them per category for easy reading.  Read on – some of them might just save your life. :)
Rules of Thumb by Tom Parker
Business & Finance
  • When making presentations,  you need to make your key points three times if you expect your audience to remember them.
  • When negotiating for money, pay attention to when your opponent’s increments of change begin to decrease in size, that’s when he or she is close to a bargaining limit. (Jeff Furman, business consultant)
Health & Fitness
  • Gym excuse. If your symptoms are above the neck (stuffy nose, sneezing) its okay to exercise. If your symptoms are below the neck (chest cough, muscle aches and pains, intestinal), its best to skip it. (It was timely when I read this because I was actually thinking of skipping my fitness training the next day because I had stuffy nose. Haha...) 
  • If you’re not going through four toothbrushes a year,  you’re not brushing your teeth enough.
  • How to estimate your marathon time -  Multiply your best ten-kilometer time by 4.65. (Jack Daniels, physiologist)
  • How to look for your dominant eye - make a circle of your thumb and forefinger about six inches in front of your face. Look through your circle with both eyes at an object across the room. Now close one eye; if the object stays in the circle, the open eye is your dominant eye. (Donald H. Dunn)
Home
  • To cook rice, rest the tip of your index finger on top of the rice and add enough water to reach your first joint. This works for any size pot. (And I thought only Pinoys do this!)
  • Getting a grip on portions. To estimate the amount of food you should eat in one sitting, clasp your hands together. The meal should be no bigger than your hands. If it is, your eating more than your body needs. (Uh-oh, I’ve been eating more than what my body needs! Tsk…tsk…)
  • Expecting guests. Plan for only half of those you invite for a large social gathering. But expect a 90 percent turnout if you’re inviting a small, select groups of friends and family.
  • When moving to a new home, set your bed first. By the end of the day you’ll be glad to have a comfy place in which to pass out. (Jeremy Reid, graphic designer)
  • Streamlining your book collection. If you don’t remember what book is about, You don’t need it, donate it or give it away.
  • When you’re moving into a new house, the possessions you get rid of should be equal to at least one third of the possessions you keep.
Photography
  • If you think you blinked during a photo, close your eyes and see what color spot you see. If the spot is white, you didn’t blink. If the spot is red, you did. Because the eyelid has many capillaries, they will render a red spot if the flash went through them. (John Zappulla)
Green Living
  • Every full bus keeps 40 cars off the road.
  • One large tree has the cooling power of five average air conditioners running 20 hours a day. (Debra Prybyla, writer)
Shopping
  • If it doesn’t match anything you own, don’t buy it. It will never match anything you own. (Stacy London, fashion expert)
  • Knowing where to spend money. Never go cheap on your bed or your shoes. You will be in one or the other your entire life. (David Schaner) 
Safety & Survival
  • Sniffing out a fire. Direct your fire extinguisher at the base of the flames from a distance of less than ten feet. If you can’t get any closer than ten feet, the fire is probably too large for a handheld fire extinguisher. (Norman Lewis, volunteer fireman)
  • Escaping a crocodile attack. Zigzag to outrun a crocodile.
  • Bank robbers escaping by car will more likely turn right than left because they don’t want to waste valuable time waiting for cross traffic to clear. (Paul LaVasseur, police officer)
  • Fleeing a bear. Bears can outrun, outclimb, and outswim a human. Your only chance is to run downhill; the bear’s center of gravity makes it difficult for it to follow.
  • When exploring a cave, always have at least four people for any caving expedition. If someone is injured, two people can go for help while one stays with the injured spelunker. That way, no one is alone in the cave. (David McClurg, speleologist)
  • Driving in a foreign country? Slow down for donkeys, speed up for goats, and stop for cows. Donkeys will get out of your way, its difficult to hit a goat, and it’s almost impossible to avoid hitting a cow. (P. J. O’Rourke, author)
  • Avoiding a crash in a car race. Aim your vehicle for the spot where the car first spun out. At high speed, nothing stays in the same place for so long. The car will have moved by the time you get there. (Joie Chitwood)
