Introduction
• Go ahead and multiply the number 8,388,628 x 2 in your head.
• There is a young man who can double that number 24 times in a few seconds.
• There is a boy who can tell you the exact time of day at any moment, even in his sleep.
• There is a girl who can correctly determine the exact dimensions of an object 20 feet away
Introduction
• There is a child who at age 6 drew such lifelike and powerful pictures, she got her own show at a gallery on Madison Avenue.
• Yet none of these children could be taught to tie their shoes.
• None of them have an IQ greater than 50.• The brain is an amazing thing.
About Brain Rules
• All these rules are based on “science” not speculations.
• All rules are collected from research published and reviewed
Who cares?
Rule #1“Exercise boosts brain power”
• Strength of mind is directly related to the level of activity.
• Exercise improves cognition for two reasons:- Increases oxygen flow into the brain - Acts directly on the molecular machinery of the brain itself

Rule #1“Exercise boosts brain power”
• How much exercise is enough?• 30 minutes of cardiovascular 2-3 times a week
Rule #1“Exercise boosts brain power”
Some Tips:• Try walking while speaking on the phone.• Try Parking away from the destination.• Try taking the stairs instead of elevators.
Bottom line: simple things do make a difference
Rule #1“Exercise boosts brain power”
Exercise is the “one” factor that can predict how well we will age.
Exercise benefits the whole body.

Rule #4“We do not pay attention to boring
things”

Rule #4“We do not pay attention to boring
things”• How would that affect software development?• “"A specification that will not fit on one page of
8.5x11 inch paper cannot be understood." • What do we feel when hearing that new project
must be:– Scalable– Maintainable– Etc.
Rule #4“We do not pay attention to boring
things”• Fully understanding an average software application
requires enormous capacity to absorb and relate details.
• No one is intelligent enough to program a computer without simplifying the task.
• Worst Programmers refuse to realize it and try to keep everything in their head. They ultimately fail. Their ego prevent them from being better programmers.
• The more you realize your limited capabilities, the better programmer you are.
Rule #5“We need to repeat to remember”
People usually
forget 90
percent
of what they learn in a
class within 30 days
Talking
about an event immediately after is has
occurred
enhances memory
for that event

Rule #7“Sleep well to think well”
Loss of sleep hurts attention, executive function, immediate memory, mood, quantitative skills, logical reasoning, general math knowledge and even motor dexterity.
Rule #7“Sleep well to think well”
• When we’re asleep, the brain is not resting at all. It is almost unbelievably active! It’s possible that the reason we need to sleep is so that we can learn.
• Sleep must be important because we spend 1/3 of our lives doing it!
• We still don’t know how much we need! It changes with age, gender, pregnancy, puberty, and so much more.
Rule #7“Sleep well to think well”
• Napping is normal. Ever feel tired in the afternoon? That’s because your brain really wants to take a nap.
• Taking a nap might make you more productive.
• In one study, a 26-minute nap improved NASA pilots’ performance by 34 percent.
• Don’t schedule decision meetings at 3 p.m. It just doesn’t make sense.
• In almost every way it can be tested, chronic stress hurts our ability to learn.
• Specifically affected are the skills needed to excel in school and business.
Rule #7“Stressed brain do not learn the same
way”
Rule #7“Stressed brain do not learn the same
way”Chronic stress:• Dangerously deregulates a system built only to deal with short-term
responses.• Creates too much adrenaline, leading to high blood pressure, and
elevating the risk for heart attack and stroke • Ravages parts of the immune system involved in producing antibodies.
Rule #7“Stressed brain do not learn the same
way”How does that affect software development:• “Adding people to a late project makes it even later” . • Working in noisy offices• Project Heroics “we will work on Weekends, stay late to finish on
time”.
