The experience of going to the toilet may change forever. Indian American scientist-led team from Stanford University has developed a disease-detecting "precision health" smart toilet that can monitor users for multiple signs of illness. The toilet can detect a range of diseases in the user's stool and urine, including some cancers. Lead author Sanjiv Gambhir said that to make sure the toilet can differentiate between different users, they have made a flush lever that reads fingerprints. The new tech could be another in the list of health monitoring devices like smartwatches.
