How could meds be poisons?

Often we see on the label of certain medicine is a poison sign and yet its an antidote.how can poison cure us?i'll tell you how.we are suppose to take in small portion or the indicated dose.but then again,everything that is too much can make you sick.does that mean we have to put poison signs on everything?

NO DIMWITS!

we are human.we have brains.think!

but the reason im writing this post is because i NEED to talk about a 'medicine' that is turning into a 'poison'.what is that?

FACEBOOK.....

notice how facebook is there to actually help us communicate with people easily,meet new people and search old lost friends etc etc.BUT i noticed how facebook is turning into a 'stalking engine'.DO WE NEED TO KNOW WHAT OTHER PEOPLE WROTE ON ANOTHER PERSON'S WALL???

i know we could hide those things from certain people but then again,DO WE NEED TO KNOW WHAT OTHER PEOPLE WROTE ON ANOTHER PERSON'S WALL???

i know sometimes we need to know what's the conversation between two person which eventually involves you but again i ask,DO WE NEED TO KNOW WHAT OTHER PEOPLE WROTE ON ANOTHER PERSON'S WALL???

now use your micro brain and think
