There have been a lot of times in my life where I've wished I could go back in time. Even if the rules stated that I could only go back to times and places I actually lived in, there are still a lot of hassles I could go back and avoid.
Like, imagine having the power to know exactly which days would be the worst and planning all your days off around it. It's like a cheat code to life.
And it's exactly the cheat code that these people really could've used.
