A cigarette is a small cylinder of finely cut tobacco leaves rolled in thin paper for smoking. The cigarette is ignited at one end causing the cigarette to smoulder and allowing smoke to be inhaled from the other end, which is held in or to the mouth; in some cases, a cigarette holder may be used, as well.
The breathing rate, or the number of times that a person breathes in and out in 1 minute, is often checked by health care professionals to determine the health of a person. The normal breathing rate is between 12 and 18 breaths per minute.
Children breathe faster than adults. Body size, weight and activity level influence normal breathing rates. But age is the factor most commonly used to determine normal values. Normal breathing rate ranges from as high as 30 to 60 breaths per minute at birth to as low as 12 to 16 breaths per minute at age 18.
