Number Our Days: Time, Attention and What Dopamine Actually Does

You pick up the phone to check the time. Ten minutes later you are still there, moving from one video to the next, without having chosen any of them. When the day ends, there is a feeling that is hard to name: it was not a bad day, but it does not feel lived either.

Many people explain this with a single word: dopamine. "My brain was hijacked," "I am addicted to dopamine." The phrase is short and gives a sense of understanding. But it says more than the research knows, and it hands us a guilt that nobody deserves to carry.

This essay does two things, slowly. First, it looks at what scientists actually measured about dopamine, and what they did not say. Then it reads a very old prayer that asks God for one simple thing: to learn to count our days. Whoever knows the value of time takes better care of their own attention.

What the Research Measured About Dopamine

Dopamine is a substance that cells in the brain use to communicate. Many people call it "the pleasure molecule." The nickname is popular, but it simplifies too much.

In the 1990s, the neuroscientist Wolfram Schultz and colleagues recorded the activity of dopamine-releasing neurons in monkeys. The best-known summary is the 1997 paper by Schultz, Dayan and Montague, published in the journal Science. The animals received a little juice after a signal. At first the neurons reacted to the juice when it arrived as a surprise. In time they reacted to the signal that announced the juice. And when the expected juice did not come, their activity dropped.

The authors' reading is that these neurons track a prediction error: the gap between what was expected and what happened. That has to do with learning what is worth seeking. It is not the same as saying dopamine "is" pleasure.

Another pair of researchers, Kent Berridge and Terry Robinson, proposed a useful distinction. In 1998 they published a review in Brain Research Reviews with one central idea: "wanting" and "liking" are different things in the brain. In experiments with rats, strongly reducing dopamine lowered the drive to go after food, but the reactions of animals tasting it remained. Dopamine seemed tied more to wanting, the drive to pursue, than to liking.

In a person's life this sounds familiar. Almost everyone has opened a screen wanting, without liking much of what came next.

What It Does Not Say

Honesty matters here. The studies above were done on animals, in the lab, with juice and food. They did not test apps, feeds or phones. Building those bridges is a hypothesis, and hypotheses deserve care.

Nor does serious research offer an "addiction to dopamine" as a diagnosis. The World Health Organization does recognize one condition tied to technology: gaming disorder, in its ICD-11 classification (adopted in 2019). Social media use has no diagnosis of its own, and researchers still debate how to measure and name the problem.

The same goes for the so-called "dopamine fast." The name suggests one could go without dopamine for a while, which the body does not allow: it is part of the brain's normal workings, including movement. Spending time away from screens may help some people, and that is a topic of its own. But "dopamine fast" does not describe what happens, and to date there are no controlled studies testing the practice.

In short, and honestly: dopamine takes part in how we seek and learn. It does not explain by itself why an hour is so easy to lose. And no research says that people who get lost in screens have a defect or are to blame. That kind of accusation only adds weight.

Counting Our Days: Psalm 90:12

What the text says. Psalm 90 carries a heading: "A prayer of Moses, the man of God." Scholars discuss whether Moses really composed it or tradition attributed it to him; the tone of the poem fits life in the wilderness and the experience of a people without a fixed home. It begins by saying that God has been a dwelling place for every generation (Psalm 90:1). Then it compares: a thousand years, before God, are like yesterday (Psalm 90:4). Human life, by contrast, is short; the psalmist speaks of seventy years, or eighty for those with more strength (Psalm 90:10). In verse 12 comes the request: God, teach us to count our days, so that the heart may gain wisdom.

What it means. "Counting our days" does not mean fearing the clock. The psalm does not end in panic. At the close it asks that the morning come with God's steadfast love, so that there may be joy through all our days (Psalm 90:14), and that God establish the work of our hands (Psalm 90:17). Admitting that the days are few serves to give them value, not to frighten. In the Bible, "wisdom" is the art of living well before God, and here it begins with a simple truth: time is a gift received, not an endless stock. God is the one who teaches; the psalmist asks, and does not order himself.

What changes in life. This part is application, not a command of the text. If time is a gift, the question about the phone changes shape. It stops being "how do I control myself?" and becomes "how do I receive well what I was given?" An afternoon with a child, an unhurried conversation, a walk, a short prayer: all of it is time that does not come back. Nobody has to live counting seconds. It is enough, now and then, to remember that the days are few and good.

Time as Care: Ephesians 5:15–16

A letter in the New Testament echoes this idea. In Ephesians 5:15–16, Paul asks his readers to look carefully at how they live, not as people who do not know where they are going, but as people with wisdom, making good use of the time. He gives the reason in a short phrase: the days are evil. The most common sense is that the world around is full of things that distract and hurt, and so it is worth paying attention. It is not a threat. The letter bears Paul's name; scholars discuss its authorship and whether it circulated among several communities.

In Ephesians 5:16, the Greek verb literally means to buy back, to rescue (hence the old "redeeming the time"). And the word for "time" is kairos, the fitting moment, not only the running clock. The idea is that each hour brings a chance to love, to serve, to be present. Making good use of time, in this sense, is not doing more things. It is living with open eyes.

This changes the conversation about attention. Our attention is part of the time we have received. Other essays in the Library already look closely at how screens compete for it; here the focus is different: what we do with the time we hold in our hands. A few small, possible steps:

• Leave the phone outside the bedroom at night, so that the first look of the day is not at a screen.
• Choose one meal a day without the phone on the table.
• Ask the device itself to show how much time goes to each app. Look at the number with curiosity, without accusing yourself.
• Set aside a small slot to read a passage from the Gospels, in silence.

None of these is a rule. They are invitations, and each person knows the size of the step that fits their life. Spending hours in front of a screen on a tired day does not change what God thinks of you.

One Possible Step

Perhaps it is worth asking, without hurry: if my days are few and a gift, what would I like to have done with this week? And what is the small gesture, of a few minutes, that brings me closer to it?

Choosing just one and repeating it for a few weeks is already a beginning. If one day falls behind, the path is still there. Psalm 90 ends by asking that God's favor rest on us; we can start again from there.
