Figure 1. Long-lived families, Identified using the Longevity Relatives Count (LRC) score, provide a unique opportunity to investigate the cohesion and interplay between genes and socio-behavioral and environmental aspects (G x E interactions). Squares are males and rounds are females. Light blue colors represent the paternal ancestors and yellow colors represent the maternal ancestors. Dark blue colors represent potential study participants. Both maternal as paternal ancestral information can be used to calculate the LRC score and identify long-lived families, thus reducing the number of sporadically long-lived persons.
