Also Venetian gondolas are slightly (by 15 cm) asymmetric - this allows to the "gondoliere“ rowing on one side.

So, all the experimental evidence shows that the matter “prefers” only one direction of chirality (and probably antimatter the other one).
And if the CPT symmetry is valid but CP brokenso this is the time arrow which is asymmetric.
So, the right question should be:
Does the time fly forward?
