How often you can take a bath depends to some extent on where you live. There are some desert countries where rain rarely falls and water is so scarce that no one could think of filling a big bath with water.
    But in most countries people can take a bath if they want to, and most of them do. In fact, for some people, particularly the Muslims and the Hindus, bathing and washing is part of their religion. Muslims, for instance, should wash themselves several times a day, before saying their prayers.
