Читаю – “…after collecting data over several years, Mike Adams (a professor of biology at ECSU) has shown that grandmothers are ten times more likely to die before a midterm and nineteen times more likely to die before a final exam. Moreover, grandmothers of students who aren’t doing so well in class are at even higher risk – students who are failing are fifty tines more likely to lose grandmother compared with non-failing students” /Dan Ariely, the (honest) truth about dishonesty/
