etymology: c.1386, "of or manifesting life," from L. vitalis "of or belonging to life," from vita "life," related to vivere "to live," from PIE base *gwei- (cf. O.Pers. *jivaka- "alive;" Gk. bios "life," zoon "animal;" Lith. gyvata "(eternal) life;" O.E. cwic, cwicu "living, alive;" O.Ir. bethu "life;" cf. also bio-). The sense of "necessary or important" is from 1619, via the notion of "essential to life" (1482). Vital statistics is attested from 1837, with ref. to birth, marriage, death, etc.; meaning "a woman's bust, waist, and hip measurements" is from 1952. Vitality is from 1592; vitals "organs of the body essential to life" first recorded 1610, from the adj., taken as a noun.
Sentence: Water and food is vital for human life.
