You lived in a Lab Station where young children like you to have data collected from them until they were 18 years old. So they have to stay in the lab system for almost 6 years. Every child have to wear a white hospital gown of some sort. The testing rooms were white empty padded rooms with a large window for scientists to look through.

(Getting data is like putting on sensors to the skin and also collecting blood)

One day, you were in your own little cell, where you sleep and basically the place that you stay when you're not being date-collected. The sun was coming up from the horizon, from what you could see through the barred window.

Then there was the sound of the door unlocking and a scientist in a white lab coat holding a clipboard came in. "Room A108, it is your time to go to the testing rooms. But first, please state your name and age to be confirmed that you are the correct child out of two thousand children."
