单词	lifespan
释义	lifespan /ˈlʌɪfspan / noun The length of time for which a person or animal lives or a thing functions: the human lifespan... As humans lengthened lifespans with better nutrition and hunting skills, childhood also lengthened. They are slow-breeding and long-lived animals, achieving lifespans of 70 years or so. I suggested that extending human lifespans might lead to extended creativity.
