One can conclude that the attributes get changed during such days. My questions:
a) What is this all about? What is this ought to be?
b) What is the benefit of this?
c) Why don't you announce such a change?
d) How can I find out ingame wether my char has a good or a bad day?
e) What does it depend on? Random? Weather?
f) Which attributes are affected when, how, for how long, why,...?
g) When do we get meters for the desire to urinate and entertainment desire?

h) Wasn't there, like, nothing more important to do...?
