This topic is nicely explained by Stephen Hawking too, in “a brief history of time”, in which he proofs how that implies that even if we have CPT symmetry (and even if we had just T symmetry), the thermodynamical arrow of time and the cognitive arrow of time (subjective time) need to have the same direction, always.
