Walking in a hospital for a regular checkup in 2020, you are greeted by a friendly android who ensured that you tap your identity card at the right reader. Following, the android handed a Ribena-like sweet pleasing drink. After finishing the drink, you take a seat at the message chair and watch half an hour of your favorite show in an individual-sized surround-sound entertainment “center”. Even before the end of the show, your test results are already ready for you.
So, as a “back-in-the-past” human, you are wondering how had the checkup proceeded. It feels more like going for a movie, with a free Ribena drink.
Actually, the Ribena drink contains the special imaging material, and the individual entertainment “center” is the imaging machine. As the imaging and analysis is so fast, the results are out in no time.
