Could the secret to better health be hidden in the thickness of your blood?
In short: Chemical engineer Sean Farrington argues that blood viscosity should be a standard medical diagnostic, similar to blood pressure. By comparing blood flow to everyday substances like ketchup and shampoo, he introduces the field of rheology as a potentially life-saving tool for modern medicine.
Rheology, the study of how matter flows, is often overlooked in clinical practice. Farrington suggests that measuring the thickness of blood could provide critical insights into patient health that traditional metrics miss. By treating blood viscosity with the same diagnostic rigor as blood pressure, doctors might identify health risks earlier.
The presentation, recorded on April 26, 2025, at TEDxWilmington, uses common household items like peanut butter and ketchup to illustrate complex fluid dynamics. Farrington makes the case that integrating these engineering principles into routine checkups could significantly improve patient outcomes if the medical community adopts these methods.
