The amount of time slower cell phone users were to resume theirnormal speed after braking.
24% more variable:
The following distance of a driver using a cell phone, as his or herattentional states shifted between driving and talking.

The Brain Doesnt Sleep to Rest
The brain sleeps to learn
Learning involving procedures and processes,
particularly, is enhanced by sufficient sleep.
Loss of sleep hurts
attention, executive function, immediate memory,mood, quantitative skills, logical reasoning, general
math knowledge and even motor dexterity.

Sleep Chronotypes
Larks: Early Chronotype (10%)
Most alert around noon and feel most
productive in morning
Owls: Late Chronotype (20%)
Most alert around 6:00 p.m. and feel most

How Much Sleep Do We Need?
Most adults need 7 9 hours of sleep per night to
function optimally
Study of soldiers found
One nights sleep deprivation resulted in a 30% loss in
overall cognitive skill and drop in performance
Two nights sleep loss resulted in a 60% drop in
performance
Five consecutive nights with 6 hours of sleep or less
resulted in performance equal to that of someone
deprived of sleep for 48 hours.
