Opportunity Cost

Choosing always means giving something up.

Shrink Definition

Opportunity cost is the value of the best alternative that's given up whenever a decision is made. Every choice has a visible cost and an invisible cost. The invisible cost is what could have been accomplished by choosing differently.

Plain language

Every "yes" quietly says "no" to something else.

Why it matters

Medical boundary

This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
