Damage to the genitals prevents the transfer of their genes to future generations and is sometimes seen as being synonymous with death.[12] Therefore, both humans and animals try to protect these vulnerable body parts from injury. In humans, certain behaviors may signal closed posture: Arms crossed on the chest or abdomen, hands clasped in front of the genitals, and crossing legs. Clothing may also signal closed posture: a buttoned suit, or a handbag or briefcase held in front of the person.
