In catastrophic injury cases, preparation should resist focusing only on the moment of injury. The jury needs a credible account of how it happened, but the lasting impression comes from the day-to-day reality of living with the injury: lost independence in basic tasks, complications of long-term immobility, the logistics of equipment and caregiving, and the loss of meaningful activities and relationships. Connecting those realities to the defendant's specific failure, such as a blind corner left in place for years despite known complaints, helps the jury see the causal link without turning the plaintiff into an advocate.
