Brain Energy and Storage Capacity

Your brain generates roughly 20 watts of power while awake, enough to light a small bulb
The brain consumes approximately 20% of the body's total oxygen and calories, despite being only 2% of body weight
The human brain can store about 2.5 petabytes of information, roughly equivalent to 3 million hours of TV
The human brain can generate approximately 23 watts of power while awake, enough to power a small light bulb
Our brain's total energy consumption during intense focus can increase by up to 50%, illustrating its high energy demand

Brain Energy and Storage Capacity Interpretation

While our brain’s power output is modest enough to light a bulb, its insatiable hunger for oxygen and calories, coupled with a storage capacity akin to millions of hours of TV, reminds us that intellectual brilliance is both a marvel and a metabolic marvel—demanding more energy than a small city in a single, concentrated mind.

Health, Maintenance, and External Influences

The human brain undergoes about 700 new repairs every day, repairing neurons and removing waste

Health, Maintenance, and External Influences Interpretation

Given that our brains perform approximately 700 repairs daily, it's as if our noggins are perpetually tinkering behind the scenes, reminding us that even the most complex machinery requires constant maintenance.
