What do I do on a Saturday if I have nothing to do and I have no freidswhat is the meaning to life?

You can watch tv or you can take a walk outside there is no real meaning to life, life is only what you make of it. Have fun doesn’t matter if you have friends or not you can always enjoy yourself

You can go to a movie,mall,arts and crafts, tv

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
