If for whatever reason you want to get a sense of the raw scale of humanity here is a fun perspective shift: there is approximately 22 million years of human life lived every day. This is equivalent to you living 300,000 lifetimes every single day. If you want to understand the math for the above it's quite simple:

• ~8 billion total population x 1 day / 365
• ~22 million years divided by 73 which is average life expectancy

This is just an unfathomable amount of life occurring at all times. The range of human experiences being lived daily surely crosses the entire spectrum of possible emotions at both the positive and negative extremes. Every single day.

Let's call this unit of measurement a Lifeday.

A Lifeday is a unit of lived experience: the total amount of human life humanity collectively lives in one day.

You've been on this page for 0 seconds. In that time humanity has lived 0 years — 0 lifetimes.

When thinking with this unit, some fun questions come up.

• How have lifedays changed over time?
• What may lifedays look like in the future?
• What would materially improve lifedays over the coming years?
• What will lifedays spend more time on in the coming years, what will lifedays spend less time on?
• What things are relatively small in terms of a lifeday now but have a huge outsized impact on lifedays in the future?
• What has remained steadily consistent over the duration of humanity?

One particular thing that became very apparent to me while thinking about this concept of Lifeday is that seemingly small conveniences and time savings for people suddenly make a lot of sense as extremely valuable at this scale. Let's take for example 5 Lifeseconds. If you saved everyone in the world just 5 seconds doing something, that is equivalent to saving 1,300 years of whatever that thing was. 18 full lifetimes. That's just one day too, it doesn't even consider if it's some gain that occurs every day from here on out.

Anything that impacts a large number of people, positive or negative, has an astounding impact. Thinking at this scale is giving me a much deeper appreciation and desire to think small, at least small in the sense of paying attention to the tiny details and seemingly invisible inconveniences that we are so used to in everyday life that still have room for improvement. Finding them is not as small as meets the eye, especially if it helps make the Lifeday better.
