The target must travel a minimum of 48 yards, no more than 52, and it must rise between 6 and 12 feet 10 yards in front of the house. Tournament shooters are handicapped according to their average and must compete at varying distances from 16 to 27 yards behind the house.
As our skin is sensitive to cold, our lips are twice more susceptible to cold. Lips do not have oil producing glands. Thus, they do not get any supply of oil or moisture during cold. Thus, lips need extra care than the rest of our body skin. Cold can make the lips go dry and chapped, giving them a bad look.
The reason can be found in the structure of the lips themselves. The lips' structure is actually different than other skin. As shown in the diagram to the left, lips do not have the same protective outer layer, or stratum corneum, found in other skin; nor do lips have the same amount of oil and sweat glands. Sweat glands add moisture to skin, but the lips' only source of moisture is saliva inside the mouth. Thus, harsh winter wind, cold, sun and dryness--indoors and outdoors--make lips more susceptible to dryness and a vulnerable target for chapping.
