Our brains give us only an approximate view of reality, because they
mix new knowledge with past memories and store them together as one.
Much like concrete, memory takes an almost ridiculous amount of time
to settle into its permanent form.
Emotions get our attention.
Aerobic exercise just twice a week halves your risk of general
dementia. It cuts your risk of
Alzheimer’s by 60%.
The human brain cannot simultaneously activate more than 2% of its
neurons at any one time. More than this,
and the glucose supply becomes so quickly exhausted that you will faint.
The brain interpolates the information coming from both eyes. It makes about a gazillion calculations, then
provides you its best guess.
We actually experience our visual environment as a fully analyzed
opinion about what the brain thinks is out there.
