For example, after using the new torso sex doll, some middle-aged and elderly people believe that their "no illness and no care" characteristics are more worry-free than "faced with diseases and aging together" in traditional marriages and loves, and even feel that the "support commitment" in traditional marriages and loves is an additional burden, which in turn challenges the traditional concept of "marriage and love are an important guarantee for dealing with life difficulties" and choose to rely on new sex dolls to spend their old age.
