Twin data and the results generated by research are driven by the behavioral and physical attributes of twin participants. However, many investigators working with twin data have limited personal contact with actual twin-pairs. This situation may be limiting with respect to interpretation of results and formulation of new hypotheses. In an attempt to rectify this issue, key aspects of the interconnected lives of co-twins in three monozygotic male twin-pairs are presented. The section that follows includes a review of twin research on Kleine-Levin syndrome, political discussion, twin relationship quality and urinary cortisol level, and guidelines for determining sample sizes. The final part of this report presents twin-related news items relating to twins' same day deliveries, death of a twin Holocaust survivor, the Vindman twins, a twin festival in France and the tiniest twins on record.
双胞胎数据以及研究所产生的结果是由双胞胎参与者的行为和身体特征驱动的。然而，许多处理双胞胎数据的研究人员与实际的双胞胎对的个人接触有限。这种情况在结果解释和新假设的形成方面可能存在局限性。为了纠正这一问题，本文呈现了三对同卵男性双胞胎中共同成长的双胞胎相互关联生活的关键方面。接下来的部分包括对克莱恩-莱文综合征双胞胎研究的综述、政治讨论、双胞胎关系质量和尿皮质醇水平，以及确定样本量的指南。本报告的最后一部分展示了与双胞胎相关的新闻条目，涉及双胞胎同日分娩、一名双胞胎大屠杀幸存者的死亡、温德曼双胞胎、法国的一个双胞胎节以及有记录以来最小的双胞胎。
