I discovered a personal on the go doctor, its a device like wrist band that monitors your vital signs,it also provides hints and analysis in order to improve your lifestyle.
it does the following;
measures heartrate
Blood pressure
Respiratory rate
Electrocardiogram read out
Mood and fatigue
Sleep analysis
Energy level
Sugar trend
SOS function etc

it works with the App in your phone,requires bluetooth connection, battery life is 3-5 days, no need to switch your device off as soon as it detects low activities it goes to standby mood.
the device reads your vitals as you go and send you details 24hours to your phone. if your vitals go out of normal it sends it immediately to you.
its an amazing device.
