>"people need to sleep"

Sleep is almost impossible with regular check-ups... 30 min or 60 min, don't remember. Excepting the comatose and most medicated(maybe not?), a person's sleep cycle is unable to reach REM when a stranger approaches and fiddles on regular intervals. I would think monitoring from afar(sensors, cameras) would be more beneficial, but I was informed the liability factors preclude such remote monitoring.

edit: to add context, I slept in the room on separate occasions with 2 family members. While tests were not performed, the regular checks were mandated. I was exhausted after my shifts ended.
