A lot of the elderly no longer actually see a doctor but once a year, their care is transferred to Physician Assistants or Nurse Practitioners....who have scams with local attorneys to find dementia patients, who have money and can be fleeced....one county I know has a whole group doing the lifting of family inheritances via their system. I was amazed at the amount of money they could get from anyone who has a sizable bank account.
Makes you want to take all your savings out in nickels and dump it in the ocean.
