Scars. Like memories, we all have them. When you look at a scar you might see a tumble, a fight, an operation, a reminder of that time you succumbed to youthful stupidity, survived a traumatic incident, cheated death. But these marks aren’t just cosmetic keepsakes. Scar tissue is what happens when skin heals but it doesn’t regenerate. It’s not as strong, it can’t move as well, it can’t grow hair or secrete sweat or sense the environment.
And it has long been thought that scarring, like death and taxes, is an inevitable part of being human.
