Just got a call from 573-882-3782, twice in a row. No idea who this is.
I received a voice mail from "Stephen" at the University of Missouri Senior Health Division (?) telling me my number had been randomly chosen to take part in a survey about health and health practices. Tough luck, Stephen; my health and how I handle it are my concern, not yours, whether this is a legitimate study, or not.  Enjoy getting my voice mail as I continue to NOT answer your calls. "Randomly choose" another number. Honestly; if this IS legitimate, you'd think they could find better ways to get people to participate in health surveys.
