How the chapter opens

In 1970 and 1971, as Army enlisted men left Vietnam, the military tested their urine for opiates on the way out, and almost eleven in every hundred tested positive. In September 1971, a research team led by Lee Robins drew a random sample of the men departing that month, added a second sample of men whose departure tests had been positive, and set out to interview them after they got home.

What the interviews found about Vietnam was alarming. Before arriving, fewer than one man in a hundred had ever been addicted. In Vietnam, almost half tried narcotics and a third tried heroin, which was cheap, pure and easy to find. One in five said that at some point there they had felt strung out or addicted, and the team checked frequency, duration and withdrawal before accepting the claims.

Mismatch card

The system

The reward system (dopamine-driven wanting) and the attachment systems that bond, grieve and seek a role.

What it expects

Rewards that are scarce, variable and diluted; a partner and a small group met every day; losses mourned with others; a role the group depends on.

What it gets

Pure, cheap, constant drugs and betting on a phone, with close relationships, mourning and purpose left to arrange themselves.

What happens in the gap

Substance use disorders in about 15 percent of Americans aged twelve and over, just over half of them mild; a rise in mortality after bereavement, sharpest in the first months and in men; higher mortality with low purpose in cohorts.

The handrail

Tend the closest relationship; keep a recurring role; change the setting and use the treatments that work; lean on people after a loss (ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.)

Strength of evidence

ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials. The treatments for addiction, couples and prolonged grief rest on trials; the links from relationships, purpose and belonging to longer life rest on large but confounded cohorts.

Popular claims this chapter tests, each with the book's verdict and grade.

The protocol

Each action carries the book's evidence grade. How the grades work.

Start here

There is one action for each part of this chapter. Skip any that do not fit your life.

  1. Invest in the quality of your closest relationship, and get couple therapy if it is in trouble

    ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.StrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.

    How: set a fixed, phone-free time together each week, even half an hour after the children are in bed, and when an argument turns hostile, stop and come back to it later. If the relationship is distressed, find a couple therapist, or start with a structured online program such as OurRelationship if cost or access is a barrier. Why: quality, not status, carries the health link, and couple therapy has large effects.

  2. Take on a recurring role, about two hours a week

    ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.

    How: a volunteering shift, a standing commitment to a person or a group that meets regularly and expects you, a project that would go undone without you. Put it on the calendar like a class. Why: purpose and regular volunteering are consistently linked to lower mortality, though no trial has shown they cause it.

  3. If a substance or habit has a grip, change your surroundings, and ask about medicine alongside it

    ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.for the settingStrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.for the alcohol medicines

    How: take the supply out of the house, change the routes, places and company tied to use, and put something rewarding in the gap, ideally something with people in it. If you have been drinking heavily for a long time, talk to a doctor before you stop. If you drink too much, ask a doctor about acamprosate or naltrexone; for opioids, ask about methadone or buprenorphine. Your doctor sets the dose, and before starting naltrexone, tell your doctor about every medicine you use, especially opioid painkillers. Why: the veterans' surroundings changed and most stopped, and the medicines help many who need more than that; a new setting does not replace treatment for a moderate or severe disorder.

  4. After a death, lean on people

    ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.

    How: accept help with meals, errands and paperwork in the first weeks and months. **If grief still dominates daily life six to twelve months on, ask for grief-specific therapy (StrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.),** such as complicated grief treatment. Why: most people adapt without treatment, and for those who do not, a targeted therapy works.

Then, pick from this menu

  • **Try a mutual-help group, or ask for twelve-step facilitation (StrongEvidence grade: Strong. Multiple randomized controlled trials, or consistent large cohort studies with a well-understood mechanism.).** It is free and at least as good as other therapies for drinking.

  • **If you bet, keep betting apps off your phone, set deposit limits, and never chase losses (EmergingEvidence grade: Emerging. Early, small, animal-only, or actively contested.).** Young men carry most of the risk. These tactics follow from the risk data; nobody has tested them.

  • **Take thirty days off a behavior that has stopped feeling like a choice (EmergingEvidence grade: Emerging. Early, small, animal-only, or actively contested.).** This is ordinary overuse territory, such as a game, a feed or a nightly drink. It is not a treatment for dependence, and not for heavy, long-term drinking: see Safety.

  • **If you are at high risk of heart disease, keep taking your medicines in the days after a loss, and treat chest pain as an emergency (ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.).**

  • **Treat depression that comes with grief (ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.).** An antidepressant added to grief therapy eased depressive symptoms, though not the grief itself.

  • **Take an awe walk once a week (EmergingEvidence grade: Emerging. Early, small, animal-only, or actively contested.).** Fifteen minutes outdoors, looking for things vast or new.

  • **After a loss, mark it with a ritual of your own (EmergingEvidence grade: Emerging. Early, small, animal-only, or actively contested.).** Something small and repeated, on a date or at a place that mattered: in short experiments, rituals eased grief even for people who did not believe in them.

  • **Aim for sex that satisfies you both, not a quota, and raise sexual problems with a clinician (ProbableEvidence grade: Probable. Good observational evidence with a plausible mechanism, or small or few trials.).** In couples, the link with well-being flattened above about once a week. From the late fifties on, half of sexually active people had a bothersome problem and few had told a doctor. New erectile problems also warrant a heart check (Chapter 16).

If this is you

Night shifts

the 3 a.m. break is where the cigarette and the energy drink live, so plan a replacement for that break specifically.

New in a city, and dating

there is no health reason to settle. Put your effort into two or three people you see often, and let the apps be one route among several (Chapters 11 and 12).

Young children at home

your time together can be short and at home, after bedtime. An online couple program with coach calls fits around children more easily than weekly appointments.

Perimenopause

if desire or comfort changes, raise it with a clinician early rather than waiting; Chapter 15 covers the transition.

After menopause

in the national survey of adults aged fifty-seven and over, low desire and vaginal dryness were among the commonest problems women reported. Both are worth raising with a clinician.

Widowed or bereaved

the first six months are the riskiest for your own health, especially for men. Keep your appointments and medicines, and let people in.

Someone you know is bereaved

offer a specific job, a meal or an errand, and keep offering into the third month and beyond.

Over 50

sexual problems are common and rarely discussed with doctors; raise them. If walking hurts, choose a seated role: tutoring, phone befriending, the paperwork for a club.

Someone you love is using

the treatments above work for them too, and for opioids, staying on medication is linked to far lower death rates. Helping them get to a prescriber may be the most useful thing you do.

Tight budget

mutual-help groups, volunteering, rituals and awe walks are free, and a structured online couple program costs far less than therapy.

Short on time

pick one, a weekly role or one protected evening with your partner, and keep it; the evidence is for regular roles, not occasional ones.

Safety

If you have been drinking heavily for a long time, do not stop abruptly without medical advice, because alcohol withdrawal can be life-threatening. Do not use weight-loss drugs of the semaglutide type to treat drinking outside a trial or a doctor's care: in three small trials heavy drinking tended to fall but other drinking measures often did not, and the drugs are not approved for this. Couple therapy is not the right first step where there is violence or coercive control; the person at risk needs individual safety support first. If grief or anything else brings thoughts of suicide, get help now: call or text 988 in the United States, or your local emergency number. Do not stop a prescribed medicine without your clinician.31

The skeptic's box

What could overturn this chapter, from the chapter itself.

Much of this chapter rests on observational evidence. The veterans were not randomized, and the few who entered treatment were probably the most severe, so the study cannot show that treatment is useless, only that setting mattered. The purpose, volunteering and religion findings share one weakness: illness lowers participation before death, and people who volunteer or attend were healthier to begin with. The health benefits of good relationships are small and correlational, and the sex trends rest on self-report. The harm from sports betting is not settled either: one small American study that followed bettors for two years found no clear change in problem gambling. The strongest evidence here is for the treatments, which all have trials. Open questions remain: whether addiction is best seen as a brain disease, a hijack or deep learning, and how much of the veterans' recovery would carry over to people who became addicted at home, among their own cues.32 If large cohorts that tracked purpose before illness found the link vanishing, the Meaning section would shrink to a matter of taste, and that would be worth knowing.
