A home is a place of residence or refuge comfort. It is usually a place in which an individual or a family can rest and be able to store personal property. Most modern-day households contain sanitary facilities and a means of preparing food. Animals have their own homes as well, either living in the wild or in a domesticated environment. As an alternative to the definition of "home" as a physical locale, home may be perceived to have no physical definition-instead, home may relate instead to a mental or emotional state of refuge or comfort.
There are certain cultures in which members lack permanent homes, such as with nomadic people.
