A woman in Dallas named Misty Vaughan was sick last Sunday.  And her fever was so high, she passed out. (We’re not sure how old she is, but she looks like she’s in her early 30’s.)

She thinks she had the flu, and says the last thing she remembers is looking at a thermometer . . . which said her temperature was 105.  Then she blacked out.  Misty’s husband happens to be a doctor, but he was at work at the time.

Luckily their four-year-old son Camden was home with her . . . realized she was in bad shape . . . and ended up saving her LIFE.

Check this out.  He grabbed her phone . . . managed to unlock it . . . went to her favorites list . . . saw his dad’s photo at the top . . . and pressed it to call him.

Eventually doctors at the E.R. managed to get her fever down.  They think she might have had a seizure.  But because she got there fast enough, she’s expected to make a full recovery.
