MRM

Yes, but it involves painfully pricking fingers repeatedly. And much more often than normal, with swimming and the excitement of a cruise. (As you can imagine, these areas become more tender. And over, even a short time, can develop the need to prick deeper to reach a blood sample.) Internet sends the readings to his phone, which enables transmission to a parent's phone, allowing the parent to make adjustments in insulin, food, activity, etc. Honestly, in my opinion, it's like charging someone for the electric to plug in an oxygen machine or even a cpap.
