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!
Flu and the common cold are different illnesses, although they may share some symptoms. You tend to feel much worse with flu, often being confined to bed for several days, whereas a cold will usually just make you feel under the weather. Flu and the cold are both caused by viruses, but completely different ones. There are hundreds of viruses that can cause colds, but only three strains that cause flu. People with flu normally feel very unwell for two or three days, and will continue to experience symptoms for around another five days.
