t or f

False because, Abraham Maslow developed his hierarchy of needs by studying all kinds of people, in fact, most of his subjects have an active career using only unhealthy subjects will screwed up his samples ( he included career and achievement on his hierarchy). 

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
