tracking

I am looking at attaching a GPS tracker to my son's Scanner, as he has multiple conditions and has managed to lose a scanner. I am unsure if this will have any effect on the scanners ability to do its job of reading and so on. Or if anyone can give me any suggestions.

Can someone help me with advice - best way to track my glucose, medication taken, sleep patterns, food and exercise. I am having problems with sleep due to sweating - we can't track down what its due to being I have a number of medical issues all going on at the same time. Possibly tracking...
