  • Hey, Vsauce. Michael here. And thank you for clicking on this video. But how many times

  • a day do you click? And how many times a day do you type keys on a keyboard? You might

  • be surprised by the answer. And one of the best ways to know exactly how many actions

  • you're taking per day is to use software like WhatPulse.

  • WhatPulse measures how often you do things. Keystrokes, mouse clicks. It even measures

  • the total distance you've moved your cursor. It's really fun stuff to track and,

  • of course, depending on who you are, or what day it is, or what you do, your totals per

  • day will change. But it's been found that, on average, people who use computers a lot,

  • like office workers, type around 5,000 to 10,000 keystrokes every day. And they click a mouse

  • about 1,500 to 3,000 times a day. Interestingly, computer users in the UK typed the most.

  • Sitting down and using a computer - typing, scrolling, moving the mouse - burns about 20

  • more calories an hour than just doing nothing. I mean, if you do nothing, you're still

  • using calories. It takes energy for you to exist. You have to keep your body temperature

  • where it should be, you have to breath, pump blood. To figure out how many calories it

  • takes, per day, for you to just exist, simply take your weight in pounds and multiply

  • it by 11. If you want to be more specific, take your weight in kilograms and multiply

  • it by .02. What you wind up with is the number of calories it takes, per minute, to keep

  • you existing. That's the number of calories that you burn every minute doing nothing.

  • It's not very much. And using a computer doesn't raise it that much higher, but don't be discouraged,

  • because typing and texting can bind us together.

  • We text and type on keyboards a lot. And rapidly. In fact, every day, 6 billion text messages

  • are sent. And there are only 7 billion people on Earth.

  • And that's just texting. We'll add keyboard typing in a little bit later. But I want

  • to take a quick detour and talk about the letters, and the characters, and the keys themselves.

  • They're not all pressed the same number of times. Some are more common than others. Let's

  • begin visually. This is a sculpture of a keyboard, where every letter has been raised to a height

  • that corresponds to its popularity compared to the other letters. The letter "E" is the

  • most common letter typed in almost every language that has a letter "E."

  • But to figure out letter frequencies in texts that you type yourself, use Patrick Wied's

  • heat map. On this site you can type a sentence in and see how frequently the characters are

  • used. For instance, this sentence contains every letter in the alphabet at least once,

  • but it uses "E" and "O" the most.

  • Roughly speaking, and considering different languages, of all the characters typed, or

  • tapped on a phone everyday, about 9% of them are the letter "E," which is a lot, but the

  • letter "E" is not the most common key. The space bar is the most commonly pressed key -

  • nearly twice as popular as the letter "E."

  • Now that we know about the space bar's popularity, let's return to texting and add in keyboard

  • typing. If we assume that about 350 million people are typing 5-10,000 characters a day

  • on keyboards, and add that to the number of characters being texted everyday, we can do

  • a little bit of math and determine that at any given second, here, on Earth, the space

  • bar is being pressed 6 million times.

  • 6 million spaces bar a second! What a great world, right? Well, let's think of it this

  • way. Because it only takes 1/10th of a second to tap, or type, a space bar, when you push

  • the space bar, statistically speaking, as many as 600,000 other people on Earth did

  • that at the exact same time that you did.

  • So, if you ever feel alone, just give yourself some space and know that more than half a

  • million people are doing that exact same thing.

  • And as always,

  • thanks for watching.
