Many CFS symptoms are the same as those from hyperventilation. Buteyko suggests you test yourself with his controlled pause: Sit comfortably in an upright chair, breathe in normally and out holding your nose after the out breath. Count the seconds using a watch until you feel you have to breathe in again. The number of seconds counted gives your control pause. The ideal pause is 60 seconds, but a pause of 40-60 denotes good health. (Editor's note: 60 seconds seems too long!
A comb is a fleshy growth or crest on the top of the head of gallinaceous birds, such as turkeys, pheasants, and domestic chickens. Its alternative name cockscomb (spelling variations abound) is because combs are generally larger on males than on females (a male gallinaceous bird is called a cock).
Perhaps a simplistic review of what a chicken is could be helpful in understanding some of the hows and whys in poultry incubation, production, management, and health.A chicken is a bird. One of the features that differentiate it from most other birds is that it has a comb and two wattles.The comb is the red appendage on the top of the head, and the wattles are the two appendages under the chin. These are secondary sexual characteristics and are more prominent in the male. few other birds have a comb or similar appendage, in some cases bearing a different name such as helmet in the guinea, and a few have wattles with some having a single median one rather than a pair. The comb is the basis of the Latin name or classification of chickens.
