I'm not sure how difficult this riddle is, but hopefully it's enjoyable!
I go up and down, and am all around,
but not many seem to know.
But if I crash and burn, to the ground,
the world may ceases to flow.
For my existence has become a medial role,
that people may try to ignore.
But those that dare play with me,
their lives can improve or turn sore.
When I go up and down words are thrown around,
as people think they might know.
But when the time goes by and my job is done,
the words of the 'wise' start to show.
What is the rhyming riddle referring to?
To try and keep things along the right path, here is a small hint:
Do not take the expressions too literally. (I.E lives turning sore is not meant to be restricted to just physical harm to someone.) Some of these expressions may contain some flare or were used more-so for the rhyming scheme but are still applicable (in some form or another).
