Using previous radial velocity surveys of the EMSS stellar sample which have identified most of the detectable active binary systems, including X-ray luminous RS CVn type systems, we have selected a sample of apparently normal, mostly single EMSS stars with spectral type comprised between F5 and K8. We have studied this sample by means of high resolution spectral observations with the aim of measuring their photo- spheric Li abundances and, therefore, their age distribution. Our results support the hypothesis, based on a model of the stellar coronal component of the Galaxy, that, to be consistent with the accepted values for the stellar birthrate in the last billion years, a considerable fraction of the "normal" yellow stars detected in the EMSS must be young objects with ages comparable to the Pleiades.
