Don't mess with people carrying Nongfu Spring.

"If you are not a pure life-focused person, sorry, you are not my friend."

On today's internet, the most viral label is no longer "Just got off the plane in the US", nor "INTJ / C9 / US Master's graduate", but "pure life-focused person".

The four characters of "purely living for daily life" are all indispensable.

Living for daily life is a state, while purely living for daily life is a state of mind.

Reject forced flattery and unrewarding efforts, reject the myths created by the internet, reject the anxiety brought by the social clock, stop pretending, stop comparing, so what?

I just want to live my own life well.

Previously, people thought that a viral meme would only take a few months from its emergence, spread, peak to fading. Internet memes are like huge waves, coming one after another — for example, who still remembers SBTI by the Daming Lake?

However, the meme "purely living for daily life" seems to have exerted far more influence than expected.

Many life-focused people are no longer satisfied with showing themselves through their lifestyles, and have directly started to pursue value sublimation at the theoretical level.

It has even spawned a situation of a hundred schools of thought contending —

I declare that the internet as a whole has entered the era of "grand theories".

And the starting point of all this has to be traced back to the most simple and basic theory.

Big Water.

01 Have you drunk Big Water today?

What is Big Water?

The proposal of this theory can be traced back to the "Godfather of Big Water", the blogger @Chang'an Erqiu.

He pointed out that "Only weak people drink beverages, while strong people all drink 1.5 to 2 liters of Big Water"!

Low unit price, large capacity; easy to carry around, place it on the desk, drink it all day long, affordable and cost-effective.

Everyone in the comment section actively participated in the theoretical construction and supplemented various arguments (in no particular order):

First of all, one bottle of Big Water can almost meet the daily water intake requirement, which is very healthy.

Secondly, it saves the time of fetching and buying water, improving efficiency and concentration.

In addition, it can automatically trigger the "happiness concession" of others: when you carry a bottle of Big Water, it shows that you are in excellent mental state, and no one dares to mess with you.

You can even do bird fly exercises on the go, link up with the "lean muscle theory" to build lean muscles as soon as possible.

Everyone who sees it will praise you for being good at managing your daily life.

All people drink Big Water, all people enjoy great health, and great health is the great result.

For a while, everyone began to seriously practice the Big Water theory.

Many enterprises have also begun to implement the Big Water theory.

The largest Big Water I have seen so far might be this one:

The Big Water theory is arguably the greatest theory in the field of internet life in 2026...

Is it?

Wrong, a single flower does not make spring, while a hundred flowers in full bloom bring spring to the garden. When all beauties are cherished and shared, the vitality of theories can be fully demonstrated.

Then the next one coming to us is,

Big Sleep Theory!

The Big Sleep Theory believes that sleep is the health indicator that people should pay the most attention to.

People who lack sleep not only have poor mental state, but also have problems in many aspects such as memory, muscle recovery, immune regulation, and emotion regulation.

Without good sleep, how can you live a good life? How can you drink Big Water?

Once upon a time, many young friends went astray: they clearly had the conditions to go to bed early, but took staying up late as their medal; they clearly knew that staying up late was bad for their health, yet they stayed up late carefully while feeling guilty.

(Friends who have to stay up late to work are not included here, you have worked hard...)

This value orientation should be completely nailed to the pillory.

Implementing the Big Sleep Theory means ensuring at least 7 hours of sleep every day.

It means completely eliminating sneaking less sleep, missing sleep, and staying up late.

It means taking going to bed on time as the top priority of life. Stop scrolling through your Red Fruit and Tomato apps when it's time, and go to sleep immediately.

Then there is also:

Big Vegetable Theory!

You should eat 300 to 500 grams of vegetables every day to meet the daily dietary fiber needs.

Later, netizens found that just eating vegetables is not enough. For example, although lettuce is crisp and refreshing, its dietary fiber content is extremely low.

Some people even specially made a dietary fiber content table to make it convenient for practitioners of the Big Vegetable Theory to follow the guide.

Remember to eat vegetables in big bites, eat more vegetables, eat enough, and you can also cooperate with the Big Water theory to drink water in big bites and drink enough.

Later, it even derived... Big Poop Theory.

This theory believes that theories such as Big Water, Big Sleep and Big Vegetable only involve one aspect of health.

And the KPI assessment of healthy life ultimately falls on... pooping.

The words are crude but the logic makes sense (although it is really too crude).

In short, there is no theory that cannot be proposed, only theories that you cannot think of.

I declare that all internet users have entered the era of grand theories.

But putting aside the contention of a hundred schools of thought, we still return to the starting point of the story — the Big Water theory itself —

Why did "Big Water" become so popular overnight?

02 Eight glasses of water a day VS drinking Big Water every day

Apart from the meme factor, some netizens tried to summarize the essence of various "grand theories" and drew a negative opinion:

Various grand theories actually package the simplest common sense in daily life into a seemingly noble but extremely simple and crude term.

It can be called the fancy version of the Earth Online novice village tutorial.

Although it makes sense to disassemble the core of the grand theory in this way, it ignores a key link:

Even if your mother tells you the health common sense a thousand times, you may not listen to a single word.

But when you mention Big Water, Big Sleep, Big Vegetable, Big Poop... people will readily accept it and can't wait to try it.

Is it really just rebellion?

Compare the common health advice "drink 1500 to 2000 milliliters of water every day", or the simpler and more commonly used "drink eight glasses of water every day", what is the difference between it and the Big Water theory?

If we analyze the two sentence patterns, we will find that "eight glasses of water a day" as an imperative sentence, its implicit subject is actually "you".

Which is "(You need to) drink eight glasses of water a day".

Behind the Big Water theory, the sentence "strong people should drink Big Water", this seemingly joking sentence contains a hidden self-motivation, that is:

"(I want to) drink Big Water every day", the subject is I.

The former seems to calmly explain how much water a person should drink to stay healthy, but actually treats people as a passive object that is imposed with requirements.

The Big Water theory turns it upside down.

Health is a goal, and it is a noble "grand" goal, something that a strong person should achieve, and I will achieve it, and thus become a "strong person".

One is a requirement, the other is motivation.

Even for the same content, the effects are of course different.

Besides, the motivation of the Big Water theory is so simple: as long as you pick up the Big Water and finish it every day, you can be healthy and become stronger.

Simple, easy to get, no additional conditions, just do it.
