In Gohringer v Hernandez-Lazo, the Court discussed the crumbling skull doctrine.
 It is trite law that the general purpose in assessing damages is to restore the plaintiff to their original, or pre-accident, position. Through an award of damages a plaintiff is entitled to be restored to his or her original position, but they are not entitled to be placed in a better position: Athey v. Leonati, 1996 CanLII 183 (SCC),  3 S.C.R. 458 at para. 32, 140 D.L.R. (4th) 235. Generally speaking, this requires the court to determine the plaintiff’s original position and position subsequent to the negligent act, and award damages to reflect the difference: Athey at para. 32; Barnes v. Richardson, 2008 BCSC 1349 (CanLII), 2008 BCSC 1349 at para. 84. In situations where the plaintiff has a pre-existing condition the thin skull or crumbling skull rule must inform the court’s assessment of damages.
 In a thin skull situation, the plaintiff’s pre-existing condition has not manifested, or in other words is not active or symptomatic, prior to the event in question. As the tortfeasor takes his or her victim as they find them, the tortfeasor is liable for all injuries even if the injuries are “unexpectedly severe owing to a pre-existing condition”, as a result of their actions: Athey at para. 34.
 In a crumbling skull situation, as in this case, the plaintiff has a pre-existing condition which is active, or likely to become active. The pre-existing condition “does not have to be manifest or disabling at the time of the tort to be within the ambit of the crumbling skull rule”: Barnes at para. 89, citing A. (T.W.N.) v. Clarke, 2003 BCCA 670 (CanLII), 2003 BCCA 670, 22 B.C.L.R. (4th) 1 at para. 62. In crumbling skull situations, the defendant is only liable for damages caused by the accident and responsible for returning the plaintiff to their original position. As Major J. stated in Athey: the defendant is liable for the additional damage but not the pre-existing damage: at para. 35. The defendant is therefore not liable for the effects of the pre-existing condition that the plaintiff would have experienced in any event: A. (T.W.N.) at para. 52. If there is a “measurable risk” that the pre-existing condition would have impacted the plaintiff in the future then, regardless of the defendant’s negligence, a court can take this into account in awarding damages: at para. 35.
 I conclude there was a real and significant chance that the plaintiff’s pre-existing injuries and the injury suffered after the Accident would have shortened the plaintiff’s career as a skating instructor, regardless of the injuries from the Accident. These injuries ultimately affect the plaintiff’s original position and must be taken into account in the assessment of damages. The risk that these injuries would have reduced the plaintiff’s chosen career will be taken into account based on its relative likelihood in determining the overall assessment of damages: McKelvie v. Ng, 2001 BCCA 341 (CanLII), 2001 BCCA 341, 90 B.C.L.R. (3rd) 62 at para. 17. Accordingly, non-pecuniary damages should be reduced by 10% to reflect such a risk.
 In assessing all of the relevant evidence, I conclude the injuries continue to adversely affect the plaintiff in a number of ways and award $75,000 for non-pecuniary damages. I will deduct 10% as a contingency to reflect the plaintiff’s pre-existing condition and the effect of the subsequent knee injury.
