Murakami describes his minor knee injury in this chapter in a way that’s familiar to so many of us. Something that pops up randomly doing something completely normal, like walking down the stairs, but becomes worrisome. Luckily for him, the injury did turn out to be relatively minor and after a few days off he was back to running. How do you weigh the seriousness of an injury? Do you have steadfast rules that you hold to when determining whether to “run through” something or take time off? Do you have a tendency to be overly cautious or overly aggressive?
