For me, I will like to approach this subject from the angle of
self-awareness divide.
From the title, 'girls difficult subject to study', it implies it
is difficult for people who are not girls.
Perhaps it is the same like someone saying 'English is a difficult
subject to study' for people who do not speak English
natively.
Or.... 'it is difficult to eat chilli' for people who seldom eat
spicy food.
I would say it is very interesing because linguistic or food divide
is smaller compared to self-awareness divide.
After some time learning a new language or eating a new food, one
can accustom oneself, but it is very difficult to strip one's
self-identity and to adopt or immerse oneself in another identity
or self-awareness.
So I would say....
It is better to eat chilli.
