Why are the results of a gram stain taken from a patient important?

Gram positive bacteria will appear purple/blueish after staining. 
It is important because whether a bacteria is Gram positive or negative helps determine the species, characteristics of disease, and the best antibiotics to use in treatment. 

Because without physical activity, the body has extra "energy" if you will, and so when it is time for bed you are not tired, so you end up staying up all night. also there is probably an effect on your internal clock, which messes with your melatonin production which goes hand in hand with your sleep cycle
