Life review

Life review is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Life review rather than just read about it. In short: Life review is a phenomenon widely reported in near-death experiences in which people see their life history in an instantaneous and rapid manifestation of autobiographical memory. Life review is often described by those who have experienced it as "having their life flash before their eyes".

Key takeaways

  • Life review belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Life review to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Life review from memory before moving on to harder problems.

Reference excerpt

Life review is a phenomenon widely reported in near-death experiences in which people see their life history in an instantaneous and rapid manifestation of autobiographical memory. Life review is often described by those who have experienced it as "having their life flash before their eyes". The experience often changes the way people view their life in a profound way.

Research and phenomenology Commentators note that near-death experiencers undergo a life review in which the meaning of their life is presented to them, but also how their life affected other people, as well as an awareness of the thoughts and feelings of these people. Bruce Greyson described the life review as a "rapid revival of memories that sometimes extends over the person's entire life". The memories are described as being "many". The review may also include a panoramic quality. According to Jeffrey Long, the experience of a life review is often described from a third-person perspective.

History In the year 1790, British naval officer Francis Beaufort nearly drowned and reported experiencing a life review. In 1847, a letter by Beaufort recalling the incident was published in the autobiography of Sir John Barrow, 1st Baronet. Wrote Beaufort:

"Thought rose after thought with a rapidity of succession that is not only indescribable, but probably inconceivable, by any one who has not been in a similar situation. The course of those thoughts I can even now in a great measure retrace... our last cruise – a former voyage, and shipwreck – my school – the progress I had made there, and the time I misspent – and even all my boyish pursuits and adventures. Thus travelling backwards, every past incident of my life seemed to glance across my recollection in retrograde succession; not, however, in mere outline, as here stated, but the picture filled up with every minute and collateral feature. In short, the whole period of my existence seemed to be placed before me in a kind of panoramic review, and each act of it seemed to be accompanied by some reflection on its cause, or its consequences; indeed, many trifling events which had been long forgotten then crowded into my imagination, and with the character of recent familiarity. The length of time that was occupied by this deluge of ideas, or rather the shortness of time into which they were condensed, I cannot now state with precision, yet certainly not two minutes could not have elapsed from the moment of suffocation to that of my being hauled up."

Worked examples

Example 1 — a first encounter with Life review

Start with the simplest possible case. Write down what Life review claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Life review before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Life review ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Life review

In research
Life review appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Life review in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Life review is common in secondary-school and first-year university syllabi. It links to neighbouring topics Near-death experiences, so understanding it makes those chapters shorter.
In everyday life
Look for Life review outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Life review in simple terms?

Life review is a phenomenon widely reported in near-death experiences in which people see their life history in an instantaneous and rapid manifestation of autobiographical memory. Life review is often described by those who have experienced it as "having their life flash before their eyes".

Why does Life review matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Life review?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
