It is a bit like genetic testing isnt it. I see these ancestory sites advertising genetic testing, but once it is out of your control in a commercial setting how do you stop them selling it to insurance companies who say for example decide that based on your genetic profile you are more susceptible to bowel cancer or heart disease and then they load your insurance premiums.
In this instance the person concerned has an existing illness and was really taken by the data available out of the device and wants one to use for his own health monitoring and to record data when he does have attacks, but I am not sure if the ones I have seen are the ones he saw (including the link - thanks stickwiththetruth - try typing that without instinctively inserting spaces!)
I have flicked him your link so await his feedback.
Thanks all and if anyone knows a QF skipper with a fancy schmancy health band please post here
