> Side note: I'm really looking forward to future biofeedback tech. It'd be interesting to know my blood sugar level and heart rate at all times.

It's a neat idea, and I'd enjoy collecting all that data too.

Would this data be useful for researchers? Or is it just too much information?

And there are risks of knowing too much about your body. People can develop anxiety illnesses (such as hypochondria, which has unfortunate popular connotations but in severe forms can be distressing and expensive) when they become too aware of their heartbeat, for example. See also full body MRI scans which are pointless unless you have an idea of what you're looking for.
