Text: To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ''dairy bull'' or a ''beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.

Text: A death by natural causes, as recorded by coroners and on death certificates and associated documents, is the end result of an illness or an internal malfunction of the body not directly caused by external forces, typically due to old age. This is especially true when an elderly person has several different conditions or diseases, but where it appears that none of them alone or together may clearly lead to the death, and it is uncertain which condition was the final factor causing death. Contrary to the statement before, everything is natural at some point. For example, a person dying from complications from influenza (an infection) or a heart attack (an internal body malfunction) or sudden heart failure would be listed as having died from natural causes. Health departments discourage listing old age as the cause of death because doing so does not benefit public health or medical research. Old age is not a scientifically recognized cause of death; there is always a more direct cause, although it may be unknown in certain cases and could be one of a number of aging-associated diseases.

Question: can a young person die of natural causes?

Text: A charity shop or thrift shop is a retail establishment run by a charitable organization to raise money. Charity shops are a type of social enterprise. They sell mainly used goods such as clothing, books, music albums, home videos, and furniture donated by members of the public, and are often staffed by volunteers. Because the items for sale were obtained for free, and business costs are low, the items can be sold at competitive prices. After costs are paid, all remaining income from the sales is used in accord with the organization's stated charitable purpose. Costs include purchase and/or depreciation of fixtures (clothing racks, bookshelves, counters, etc.), operating costs (maintenance, municipal service fees, electricity, heat, telephone, limited advertising) and the building lease or mortgage.

Question: are thrift shops the same as charity shops?

OPTIONS:
- no
