Why don't you write down both sides of the meditation question and see what happens. What could you come up with that indicates that Meditation has merit and benefits those that practice regularly-any scientific research that validates this view.
Take the other side and try to discredit it as a waste of time.
Devolped by some Lazy Monk or Yogi who was high on fresh air and out of touch with reality. Sitting up on a mountain not contributing anything to society except his intangible "meditation".
I'm sure you could find a manageable arguement in there someplace.
