Past, 100% the past. Whenever I talk about superpowere with my students I'm like TIME TRAVEL! So that I can travel to the past and see / experience all the cool time periods for a day or so. And not experience the down sides like not having a 21st century toilet for more than a couple of days or weeks xD You're bored why not travel to the roman empire or hey let's kill baby Hitler.
Would you rather have 10 siblings and never have a moment of peace and quiet OR be an only child and being alone most of the time (parents being away etc.)
