The United States dietary guidelines, based on the 2005 Institute of Medicine report, recommend that the general population aim for sodium levels of 1,500 to 2,300 milligrams a day because those levels will not raise blood pressure.
One of the symptoms of the plague was coughing and sneezing, and it is believed that Pope Gregory VII suggested saying âGod bless youâ after a person sneezed in hopes that this prayer would protect them from an otherwise certain death. The expression may have also originated from superstition.
These days, one says Bless you! because it is expected, not out of concern for the wellbeing of the sneezer's soul or heart, a need to disassociate oneself from the dying, or envy for another's presumed luck. We do it because we've been taught this is an obligatory response whose omission would seem glaring.
