  After a brief review of population synthesis of close-by cooling neutron
stars, I focus on the interpretation of dichotomy of spin periods of near-by
coolers. The existence of two well separated groups -- short period
($\sim$0.1-0.3 s) radio pulsars and long period ($\sim$3-10 s) radio quiet
sources, aka the Magnificent seven, -- can not be easily explained in unified
models developed recently (Popov et al. 2010, Gull{\'o}n et al. 2014). I
speculate that the most natural solution of the problem can be in bimodal
initial magnetic field distribution related to the existence of an additional
mechanism of field generation in magnetars.
