In talking with the Shelby County Medical Examiner this afternoon, she says forget the fans, they won't really solve the problem. She says fans might make you feel better but they don't cool the body down enough to make any difference.
Dr. Chancellor says the real issue is body temperature and that people in homes without air, MUST get to someplace that is air conditioned for a few hours to reduce their internal temperature.
It looks like the real effort for the next few days needs to be looking out for people in the neighborhood who may not have air and making sure they can get to someplace to cool off for a while. They can request a free ride from MATA by calling 2-1-1, but you know that's not going to cover everybody... and there are many elderly people who just simply won't ask for help. So, check on your neighbors.
