Nopes, why should I?
If people supposed to fast to experience the hunger pain that many poor people will feel when hungry, then why do the poor supposed to fast? They already know what it is like to be hungry. And the poor can still drink water from rivers or what ever and water was not sold during those days so water has nothing to do with being rich or poor.
Yesterday I told this to a Muslim and was like:
Errr...mmmmm.. .maybe.... I DON'T KNOW! and gave me no answer!
