Why am i not tired??

cause generally i go to college and i think roughly speaking nothing adjectives day except when i can procure home and go to sleep.
but very soon im home the whole afternoon and im not tired...
why?
btw im not sick or anything Built up energy from the weekend? It is well brought-up to have get-up-and-go, maybe freshly try and excersize a bit!
do some exercises or go for a run, something that tires you out you know
