So the "Eutostropic Emulation" is one of the tasks of a 'hypersleep pod'. Your pod is actually going to be connected to you through your spine(But this is only connected while you're already sleeping and disconnects before you the pod would wake you.) and tracks the entire body by "reading" your brain which is possible because the device that is inserted into your spine can "connect" to billions of your brain connections which is enough to read your electrical Current Print*, which is the electricity in your brain, so through this connection it can cause your brain to release chemicals with "electric communications". So in your pod after about 250 years and your brain hasn't been stimulated for all that time your memory fades to zero and your brain stops releasing any chemicals and goes into shock and you have a heart attack and die... but this "Eutostropic Emulation" causes that process to reverse once it senses the brains chemical shut down by "manually" telling the brain to release large amounts of all your pleasure chemicals to resaturate your brain which puts you into a euphoric state.
