Why would the data only be used for patology?
* Diet balancig? (Hey, eat more cucumbers)
* Calories? (IANAD)
* Also more serendipiteous opportunities we can't foresee now
Or:
(at the doctor's)
t = 0 - Doc - I would need a urine analysis
t = 60s - User - Here you are.
Cons:
* Huge privacy concerns (Hey, you are fired! btw, you also have cancer)
