20. “ Multitasking, when it comes to paying
attention, is a myth
We are biologically
incapable of processing
attention-rich inputs
simultaneously

Make

errors
Take
50% longer to
complete a task
34. Exercise is not just good for
general health, it actually
improves cognition
35. “Exercise increases oxygen flow into the brain,
which reduces brain-bound free radicals [...] an
increase in oxygen is always accompanied by
an uptick in mental sharpness.
Exercise acts directly on the
molecular machinery of the
brain itself. It increases
neurons’ creation, survival,
and resistance
”—Dr. Medina
36. Even more benefits!
• Reduces depression
• Treats dementia
• Improves reasoning
• Improves long-term
memory
• Improve fluid intelligence
• Helps you solve problems
• and more...

walk or a run...
just move!

Rule #4
We do not pay attention
to boring things
55. 1. T E L E P R O M P T I N G
People tend to put every word they are going
to say on their PowerPoint slides. Although
this eliminates the need to memorize your
talk, ultimately this makes your slides
crowded, wordy, and boring.You will loss your
audience’s attention before you even reach
the bottom of your ...

56. 2. Spelling mistakes
Many people do not run spel cheek
before there presentation
BIG MISTAK!!! Nothing makes you lok
stupder than speling erors

57. 3. Bullet pointing
• Avoid • Bullet-Points
• Excesive • And
• Buller-Pointing • Your
• Only • Key
• Bullet • Messages
• Key • Will
• Points • NOT
• Too • Stand
• Many • Out
Slide from Don McMillan, “Life After Death by PowerPoint”: http://bit.ly/aYxegN
58. 4. Too many levels
• What is worst
• Too many bullet point levels are shown
• Type size gets smaller and smaller
• Until it is utterly unreadable
• Even for audiences in the 4th row
• So you better have just one bulletpoint level
• Better yet, forget about bullets (bullets, not guns,
kill people. Don’t you know?)
• Use them sparingly
• There are many other ways of detailing your ideas!

59. 5. Color schemes gone wrong
bad
color schemes can
lead to...
• Distraction
• Confusion
• Headache
• Nausea
• Vomiting
• Loss of bladder control
