American football defensive tackle Vince Wilfork reads from a weathered book titled "Words of Strength." He draws motivation from Nietzche, reciting, "That which does not kill us makes us stronger" after making a tackle on the field. When he continues on with Schiller's quote, "The strong man is strongest when alone," his teammate takes it as his cue to leave. According to independent studies, Castrol EDGE is three times stronger against viscosity than other leading motor oils. Maintaining a philosophical state of mind, Wilfork asserts that those other "leading" oils can't actually be leading if that is the case.
