yes Iftar is very heavy for a body that is ravaged all day without water and food.
Fasting the Islamic way is a sure way if killing yourself slowly but surely,hence predominantly high incidences of kidney diseases,heart attacks and malnutrition in Muslim countries yet it still goes on.
Traditions ,be it nationalistic,religious or social are our unnecessary ropes that stops us advancing humanely and solve the problems of the world that is higher priority then any religious faith.Yet the religious zealots that keep the people stupid and illiterate so they can overpower them and make them into worthless robots are the real culprits to be punished but it is big money so everybody accepts this retarded lifestyle.
