The bill of rights is still used, it is a part of our law, people refer to it a lot to why they are allowed to use things, or why they are not forced to do things. however it is unfair because the government kind of crossed the line into patriot act.. but they have all the excuses.. but it is still used.
the driving age should not be lowered, i believe that it should be increased, because of needing permission of parents, it becomes unfair. also because we are such drunks are druggies that we arnt always good.. even though tons of older people are too.
astronomy is not currently worth the time, it was worth it back in the cold war, because we had to out do the communist.. lol, but now; it should really be waited until we have better technology, so that we can get something important done, besides studying mars, or some dumb other planet/satelite.
