Life Extension Institute

Life Extension Institute 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 Extension Institute rather than just read about it. In short: Life Extension Institute was an organization formed in the United States in 1913 with the philanthropic goal of prolonging human life through hygiene and disease prevention. It is now known as EHE Health.

Key takeaways

Life Extension Institute 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 Extension Institute to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Life Extension Institute from memory before moving on to harder problems.

Reference excerpt

Life Extension Institute was an organization formed in the United States in 1913 with the philanthropic goal of prolonging human life through hygiene and disease prevention. It is now known as EHE Health. Its organizational officers included many celebrity-philanthropists such as William Howard Taft, Alexander Graham Bell, and Mabel Thorp Boardman but also genuine medical experts including William James Mayo, Russell Henry Chittenden, and J. H. Kellogg and a "Hygiene Reference Board" of dozens of nationally recognized physicians of that era such as Mazÿck Porcher Ravenel and Major General William Crawford Gorgas.

Activities A major project of the institute which fulfilled its mission to disseminate knowledge was publication of the book How to Live, Rules for Healthful Living Based on Modern Science, now in the public domain. The institute was a proponent of eugenics including sterilization of grossly "unfit" individuals:

It depends largely upon the action of those now upon the earth, who are now making their choices of marriage, as to whether the races of the future shall be physical, mental or moral weaklings, or whether they shall be physically brave and hardy, mentally broad and profound, and morally sterling. To summarize: There are three main lines along which eugenic improvement of the race may be attained:

Education of all people on the inheritability of traits; segregation of defectives so that they may not mingle their family traits with those on sound lines; sterilization of certain gross and hopeless defectives, to preclude the propagation of their type. — Irving Fisher and Eugene Lyman Fisk How to Live, Rules for Healthful Living Based on Modern Science

Worked examples

Example 1 — a first encounter with Life Extension Institute

Start with the simplest possible case. Write down what Life Extension Institute 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 Extension Institute 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 Extension Institute 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 Extension Institute

In research: Life Extension Institute 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 Extension Institute 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 Extension Institute is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alexander Graham Bell, American organizations established in 1913, Education organization stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Life Extension Institute 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.
