LifeSharers

LifeSharers 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 LifeSharers rather than just read about it. In short: LifeSharers was a nonprofit United States–based organization which functioned as an organ donation network. By agreeing to donate their organs to the network, they received priority in receiving organs from other members of the network.

Key takeaways

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

Reference excerpt

LifeSharers was a nonprofit United States–based organization which functioned as an organ donation network. By agreeing to donate their organs to the network, they received priority in receiving organs from other members of the network.

LifeSharers was founded by Dave Undis in 2002. He believed that the best way to encourage increased organ donation was to ensure those willing to donate receive priority in receiving organs. The concept has been criticized by those who believe that decisions of priority should be based on purely medical criteria. On March 21, 2016, a post on the Lifesharers blog announced that the network had shut down.

Worked examples

Example 1 — a first encounter with LifeSharers

Start with the simplest possible case. Write down what LifeSharers 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 LifeSharers 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 LifeSharers 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 LifeSharers

In research: LifeSharers 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 LifeSharers 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: LifeSharers is common in secondary-school and first-year university syllabi. It links to neighbouring topics Defunct organizations based in the United States, Medical and health organizations based in the United States, Transplant organizations, so understanding it makes those chapters shorter.
In everyday life: Look for LifeSharers 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 LifeSharers in simple terms?

Why does LifeSharers 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 LifeSharers?
