Wizards were not easily injured. At least, ordinary people did not easily injure wizards.
Magical power was a wondrous substance. Once a wizard possessed it, it lay hidden within their body. Usually, when a wizard was not using magic, their magical power served no purpose.
But when wizards faced the possibility of injury beyond a certain degree, their magical power came into play.
Thus, although wizards occasionally scraped themselves or took a tumble that left them bruised, almost no wizards actually died from ordinary accidents such as falling from a building or hitting their head on a rock.
That was why, when Harry and Hagrid first met, Hagrid had reacted so strongly when Harry told him that Aunt and Uncle said his parents had died in a car crash.
Without the involvement of a wizard's power, an accident of that magnitude was very unlikely to kill a wizard.
That was exactly what had happened to Dikin.
Although Dudley's giant windmill of a super shoulder throw had left him dizzy and caught him completely off guard, the truly lethal part-landing headfirst-had not actually injured him.
His abundant magical power had taken effect at that moment.
The impact had left a moderately deep dent in the ground. An ordinary person would probably have broken their neck, but Dikin was unhurt. What really caused Dikin trouble was Dudley's subsequent chokehold.
A wizard's automatic magical protection could prevent sudden injuries, such as a throwing knife suddenly flying at them.
But if you took a saw to their arms or legs, you could certainly have them off in minutes. Of course, a wizard could also use magic to attach them again in minutes.
Dikin's automatic magical protection was useless against Dudley's chokehold. With his neck clamped tight and over 275 pounds of weight pinning him
