well for me, when we are all telepathic our minds direct our awareness.. so we would learn to focus and direct our attention to where we want it rather than be overwhelmed with the worlds thoughts and feelings. So we can link with whoever or whatever we want.. AND lets remener telepathy works both ways, so we can send love and support to people we link with (like family) who are suffering. Actually I know this distance healing from personal experience, and some of my family are very powerful distant healers and psychics..

So yes i would say very large societal changes would occur, as well as us becoming more honest and happy people.. but initially if this happened overnight I guess it might get pretty ugly at first.. ;-)
