Did you know?

The average human brain consumes energy at the rate of about 12.6 watts, which about 20% of the consumption rate for the whole body at rest, which is 63 watts.

The brain apparently has no switches and consumes energy at that approximate rate day or night, awake or asleep and possibly even during a coma.

I suspect some are "dim-wits," and as a result consume less than 12w of power....

Happy Monday! :-)

The Math

—Resting metabolic rate: 1300 kilocalories, or kcal, the kind used in nutrition

—1,300 kcal over 24 hours = 54.16 kcal per hour = 15.04 gram calories per second

—15.04 gram calories/sec = 62.93 joules/sec = about 63 watts

—20 percent of 63 watts = 12.6 watts

Most sources agree the brain consumes ~20% of the body's power. Sources vary on body power consumption, ranging from 60 watts to over 100 watts. Again, this post was intended for light humor.

Do you agree, or not, with the 20% allocation for the brain?

The answer is in an entirely different scale.

If you're a cool cat - is your brain consuming less power?

Inquiring minds want to know

For example, in sports would there be more cerebellar activity since a lot is muscle memory?

It was about brain efficiency

If you want to assert that is political

It says more about you than me

@jeb - we never tried to break it down to that level, but having spent over 50 years on this earth (and witnessing the current administration and his supporters)"

@jimglas, I am not talking about you.

Actually, watts used to ”heat the dome” come out of the other 80% of the 63 watt total!

The subtlety of your humor is sublime!
