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!
A person infected with a cold virus may be contagious for two to three days before any symptoms appear and remain so until he or she doesn't show any symptoms. This is a period of up to two weeks or so. The height of the common cold contagious period is when symptoms are at their worst -- usually around day 2 to day 4 of the cold.
