Mina and Doctor Rebecca Witt had been discussing her invention that could potentially scan for viruses and diseases from inside of the body. The device could be connected to an outside monitor which could be accessed by a physician; telling patients their blood work results within minutes, maybe within seconds of walking into a doctor's office.
While the device was notable, Mina could only see the flaws in its application. The only people who would be willing to have such a device implanted in them at birth would be the working class. Unfortunately, people who belonged to the same class as Mina and her family seldom visited a doctor. It was just too expensive.
Mina herself avoided doctors' offices. When she was a child, her parents leaned toward home remedies for recovery, and only took Mina and her sister to the doctor for their back to school physical, and that was done at a free clinic many miles away. The truth was that they just could not afford anything else.
