A griffin is a fabulous animal, symbolically significant for its domination of both the earth and the sky - because of its lion's body and eagle's head and wings. It has typological antecedents in ancient Asia, especially in the Assyrian k'rub, which is also the source of the Hebrew cherub.
A common cold can last from 3 days to a week but never more than two weeks because then you can have something totally different from a cold, if it does last for more than two weeks I suggest going to a doctor. Depending on the severity of it, I believe that colds last anywhere from 3 to 7 days!
You can tell the difference by the length and severity of the illness and whether you've had a similar experience in the past. Both colds and flu usually last the same seven to 10 days, but flu can go three to four weeks; the flu virus may not still be there, but you have symptoms long after it's left.
