At first Jeff also planned to transform out of curiosity, but after thinking about it for a bit, he decided not to.
After having touched the "Execute" button, Jeff did not notice any change. But what he didn't know is that several people had regressed at this moment. And many of them were transformed in different ways. Some were turned into newborns, others into 1-year-old babies, and others into 2-year-old toddlers. And the way in which many of them reacted was varied. Several of them were surprised to see their new age while others were more than delighted.
One of the people that was regressed by Jeff, was a woman named Valerie. Before Jeff altered the world, Valerie was a young daycare worker, but now she's been reduced to a 2-year-old toddler girl who now attends the daycare she used to work at.
