Jarvis was a typical, middle-aged man in the early summer of 2019.
He didn't know what a transient ischemic attack (TIA) was until he had six of them in one evening.
The next day, Jarvis walked into an emergency room on his own power to get checked out.
The TIAs had been scary, but he figured they were just a warning that he needed to take better care of himself.
Six days later, an ambulance drove him home from the hospital.
He'd lost the use of his left arm and leg.
Jarvis had suffered.
