The small crack in a running influencer’s foot was declared by my FYP page with the importance of a new political bill: Mary McCarthy has a stress fracture. What does this mean for you? My algorithm was suddenly overwhelmed by content reacting to this injury. Critics declared that an outcome like this was inevitable for someone who logs 100km every week. Others jumped to McCarthy’s defence: runners frequently get injured from less, it’s just that you don’t hear about it.
