Before the fatal incision is made, the animal may be rendered insensible to pain by various methods, including captive bolt, electricity or chemical. Without prior sedation, stunning or anesthetic, this method of slaughter causes a high degree of anxiety, although other religiously funded studies contradict these findings. The captive bolt is placed against the skull of the animal, and penetrates to cause tissue destruction in the brain, incapacitating the animal so that the procedure may take place. Electricity is used mostly to
Medically unexplained physical symptoms and the death or serious illness of a close family member are significant risk factors.

The likelihood of meeting such criteria increases with the number of unexplained symptoms reported. However, anxiety and depression are also very common in individuals with medically explained illnesses, and again, the likelihood of a person receiving one of these diagnoses increases with the number of symptoms reported. Consequently, on the current evidence, we cannot infer that anxiety or depression are causes of medically unexplained physical symptoms. Physical symptoms have
