Life is full of CONTRADICTIONS!

I am sure we have come across many contradictions in life. Here are a few:

• As seen in the picture above, a notice is posted at the place where the public is told not to post any notice.
• All the harmful effects of smoking are printed on every cigarette box with disgusting and frightening pictures but they continue to be sold to smokers.
• Doctors are supposed to cure patients, but they administer "poison" to their patients. Check out the label on most medications, there is this word "POISON" printed in red.
• One philosopher ever said, "There is no truth in this world." So, there is no truth in what he said, too.
