I first received a call from an automated machine from Medical Services (?) that offered a free heart & artery scan for me and spouse ($450 value) to detect any problems with the heart or arteries (only spouse is eligible).  The message said "Dial 1 if interested", then "say your full name".  Right after I did that, they hung up.  A few days later, a man called me back and said that I'd shown interest in the procedure and that he was ready to schedule an appointment for me & my spouse.  He asked for our home address.  He was quite aggressive and persistent in pushing me to give him a date & time when both of us can come in.  He said a brochure would be mailed to us and all the explanation will be in there and the nurse will contact me to firm the appointment.  This sounds a bit fishy to me.  He did not leave a call back number.  I'll wait and see if the brochure will arrive and we'll decide whether to even show up or not.
