You are always welcome ! <| sep |> For a long time , medical doctors didn ' t want to believe that ulcers could be caused by bacteria . Maybe we will get a better understanding of the role of the intestinal environment and flora on mental health and the health of the rest of the body . I only got to take a quick glance at the paper but there seems to be nothing proving a causative relationship between mental health and physical health except that mental illness occurred earlier . For all we know , physical symptoms may simply take longer to manifest . <| sep |> It ' s like a look into the future <| sep |> It depends on which carrier you ' re coming from and what value you place on some of the fi unique features e . g . free international roaming , free data sims . That said , Fi becomes noncompetitive with many MVNOs after 2 or 3 gb . There are a number of prepaid plans that offer either 4 gb or unlimited data for $ 45 . Even TMOs regular unlimited plan is $ 70 so Fi loses any advantage after 5 gb . If you ' re on a family plan it loses the advantage with less data . Fi requires behavior changes that may or may not be desirable . If you forego streaming music and video to save money you ' re sacrificing utility . Unless you switch to Fi solely to pinch pennies or use its unique aforementioned features you ' d probably be better off with another carrier .
