Mental health is our birthright. (46) We don’t have to learn how to be mentally healthy; it is built into us in the same way that our bodies know how to heal a cut or mend a broken bone. Mental health can't be learned, only reawakened. It is like the immune system of the body, which under stress or through lack of nutrition or exercise can be weakened, but which never leaves us. When we don't understand the value of mental health and we don't know how to gain access to it, mental health will remain hidden from us. (47) Our mental health doesn’t really go anywhere; like the sun behind a cloud. it can be temporarily hidden from view, but it is fully capable of being restored in an instant. 
Mental health is the seed that contains self-esteem — confidence in ourselves and an ability to trust in our common sense. It allows us to have perspective on our lives — the ability to not take ourselves too seriously, to laugh at ourselves, to see the bigger picture,

We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them. But we have realized only recently that the identity of each sex is not so easy to pin down, and that definitions evolve in accordance with different types of culture known to us, that is, scientific discoveries and ideological revolutions. Our nature is not considered as immutable, either socially or biologically. As we approach the beginning of the 21st century, the substantial progress made in biology and genetics is radically challenging the roles, responsibilities and specific characteristics attributed to each sex, and yet, scarcely twenty years ago, these were thought to be "beyond dispute".

A. Wish to claim their rights and freedom.
