Speaking about getting some work done. And neurons.

You, as a healthy human individual, have about 200 billion neurons in your brain. Okay.

Every single one of them is single neuron is sending up to 1,000 nerve impulses every second, or 60,000 per minute.

If you multiply that with that little number of above-mentioned neuron crew in your brain, you can get 12,000,000,000,000,000 (12 quadrillions!) signals being sent throughout your brain


Let’s move to the eyes. Them blinks. Quick naps.

The average person blinks 15-20 times every minute which our brain may as a way to take a quick time out. Altogether, humans spend about 10 percent of our awake time with eyes wide shut.


The normal respiration rate for adults is about 12-20 breaths per minute. That amount of breath pumps about 6-7 liters of air (and 11ml of oxygen) into your lungs every 60 seconds, which can add up to 11,000 liters in a day.


Heart rates can vary based on your fitness level, emotions, body size, and even body position, but a normal resting heart rate for adults falls anywhere between 60 and 100 beats per minute, 40-50 if you are an athlete, let’s say. For an average male, 72.

For example, the official Guinness World Record holder for the lowest heart rate in a human is Martin Brady, 45, of Guernsey, who recorded a heartbeat of 27bpm. Daniel Green, an athlete pensioner, achieved the world record for the slowest heartbeat in a healthy human with a heart rate of just 26 bpm in 2014.

7 LITERS, again

With every heartbeat, your heart pumps (it is called cardiac output) about 70 milliliters of blood and sends it throughout your body. If you have a resting heart rate of 60-80 beats per minute, your heart pumps between 5-7 liters of blood every 60 seconds and 7600 liters per day!

By the end of your life, your heart will have pumped 1 million barrels of blood. Mind blown much? 1 million barrels! I mean… okay.


Red blood cells — also called erythrocyte, cellular component of blood, millions of which in the circulation of vertebrates give the blood its characteristic color and are tasked to carry oxygen from the lungs to the tissues. Speaking of mindblowing, that 7 liters of blood per minute is 120 million in created red blood cells, to be exact.

In healthy adults, an estimated 100 billion red cells and 400 million white cells are produced each hour. And while that seems sure to cause serious overcrowding inside your vessels, it’s actually necessary to keep up with the rate at which red blood cells wear out — about 120 days.

30,000 – 50,000

The number of skin cells you’ll shed. Every minute of your life, your valiant skin, which protects you from the elements and damage, loses a vast number of troops. If you’re having trouble visualizing how much that is, an average human can lose about nearly 50kg of dead skin over his or her lifetime.


The estimated amount of visual information, measured in bits, that your retina pushes to your brain for interpretation.

The researchers had calculated that the human retina can transmit data at roughly 10 million bits per second. By comparison, an Ethernet can transmit information between computers at speeds of 10 to 100 million bits per second.


The percentage of blood that will be cleaned by your kidneys. The waste-cleaning tag team processes and cleans the entire volume of blood in about five minutes, meaning that it tackles about 1.2 liters in 60 seconds. Perhaps this is most impressive when you consider that the average kidney only weighs about a quarter of a pound.


Centimeters of hair you’ll grow (presuming you still have some on your head.) While any individual strand of hair only grows an average of a half-inch per month — and even that may depend on race, diet, age and sun exposure — each head has about 100,000 strands. Because it’s a lot of hair growing a teeny amount, it’s still going to take a year or four to grow your hair out.


Electrical signals will be passed on by your neurons. While we can’t pretend to understand every inner working of the brain, we can tell you that experts believe the brain’s cells send billions of signals every minute. And that’s the lowest estimate. The highest estimate is something we have trouble imagining, even with all our brainpower: 17.2 TRILLION neural firings per minute.
