Questions concerning the Bose-Einstein (BEC) and Fermi-Dirac (FDC) correlations of hadrons produced in e+e- collisions are discussed. Among them the emitter dimension r as a function of \sqrt {see} and the hadron mass, the extension of the BEC by including isospin invariance and the proposed relation between r and the inter-atomic separation in Bose condensates.
