On this train, there are with you 50 monks going back to their temple on the terminal of the train. (I assume you are not a monk, and if you are, you are a very cool one to be on this forum!)
When the controler came in to check their tickets, he noticed that SOME of them had soot on their faces (their faces were dirty). And of course they cannot feel it.
So he said: "You know, there are cleaning areas at every stop we will make until we arrive. So anybody with soot on his face can have time to get off at any of them, get cleaned up, and come back before the train resumes its trip."
Now these monks are very wise, but they are also EXTREMELY lazy! So lazy in fact that they don't want to get off the train to get cleaned up unless its necessary (if they have dirty faces). They also took vows of silence untill they arrive to their destination, so they cannot say anything to each other. They don't even bother to look for a mirror or something to see their faces with. They don't even want to signal each other in anyway. They can't see their own faces in any of the windows in the train. They donb't even want to put their hands on their faces to check!
In brief, THEY DON'T WANT TO MAKE ANY PHYSICAL EFFORT UNLESS IT'S ABSOLUTELY NECESSARY NOR THEY CAN COMMUNICATE WITH EACH OTHER NOR SEE THEIR OWN FACES in any way! They can only THINK and REASON! (Sometimes a more ardeous act for some people BTW)
They can only see each other's faces while maintaining a poker face.
In this particular case there were 5 monks with soot on their faces.
The question for this puzzle is:
WHAT DO YOU THINK WILL HAPPEN?
Will they remain dirty? (I promise you they won't)
If not what?
Now I know this is not a very clear question, but remember this is the same situation these monks are in. Plus I will post future hints later on (If you need them of course)...
PS: This is not a lateral thinking puzzle nor a play on words. Just not my style...
