If frailty reaches less consensus on the definition, it is a term much more widely used than this of biological age, which shows a clearer definition but is scarcely employed in social and medical fields. In this review, we suggest that this Biological Age is the best to describe how we are aging and determine our longevity, and several examples support our proposal.engjournal article1872-9452https://doi.org/10.1016/j.mam.2024.101291https://www.sciencedirect.com/science/article/pii/S0098299724000505?via%3Dihubrestricted access616-053.9613.9857.017.8575612.68FrailtyBiological ageAgingLongevityGeriatricsGerontologyMedicinaGeriatríaGenéticaFisiología32 Ciencias Médicas3201.07 Geriatría2410.07 Genética Humana2411 Fisiología Humana
