-#    In this SAREF4EHAW example/instance (from SAREF4EHAW monitoring and support of healthy lifestyles for citizens),
-#    This use case is about a patient of around 50 years old, Bob, with overeating habit. 
-#    In the actual context of Covid-19, Bob as a risky patient is thus remotely followed/monitored/controlled by a caregiver, Dr. Knock, for Covid-19 signs detection purposes.
-#    The patient is equipped with a BAN with an android smartphone as the BAN hub, as well as three COVID-19 related devices (wearables, sensors).
-#    Bob is equipped with SpireStone wearable device for breathing rate monitoring, a ScanWatch wearable for monitoring the SPO2 level and a TUCKY thermometer for the body temperature monitoring.
