Непонятно, как?..

Heisenberg indetermination principle applied to ill luck:
The better you know the amount of ill luck that will strike you,
the worse you know when this will happen,
and vice-versa.
and Relativistic correction of Murphy’s law:
Whether things can go wrong or not, it depends on your frame of reference.
Corollary (otherwise said: ill luck is actually absolute):
Regardless of your frame of reference, things will go wrong anyway.
