Practical consequences of "being" bodies

Merleau Ponty argued that body is inextricably related with world and social activity that is inseparable. Body is not only a part of world but interact with wold to construct which is the best way to live. For example, Mother Teresa thought herself as an active part of world and did lots of work to do the world as a best place. Psychologist also need to think on this perspective to deal with people to explain not only know thyself but know the actual function of body toward society and world as well. We are not having the body but being in body, that's the way, in which we can think about being in the world, furthermore, it is impossible to live better without social interactions, meaning system and construing world as part of well being. Psychologist should emphases on individual's problem as it is the fundamental problem of society.
