The age of the Universe in the $\Lambda$CDM cosmology with
$\Omega_{matter}=0.26$ and $\Omega_{\Lambda}=0.74$ is the same as in the Milne
cosmology which correspods to an almost empty universe. In both cases it is a
reciprocal Hubble constant, $1/H_0$, that for now preferred value $H_0=71
km/s/Mpc$ is 13.7 billion years. The most curious coincidence is that at the
present time, in the $\Lambda$CDM model the decelerated expansion is exactly
compensated by the accelerated expansion, as if the Universe coast for 13.7
billion years.
