What would you change on this world if you had unlimited power for a day

and why ?<br><br>Just for context i'm working in a palliative care unit for adults, and i never saw someone on their deathbed that regret not having made more money or bought a bigger house. But often people regret not having traveled as much as they would have liked, not having spent enough time with family and friends, not having been themselves more, etc. <br><br>So i was just wondering, if you had unlimited power for a day, what would you change on this planet ?
