text: is it right that my sons' science teacher tells him that he will die by the age of 21 ? ? because of globle warming.   she also has him believeing in alians, he says that she said " out of all the planets in the unaverse, do u really think we are the only ones?"   my son loves science but i just don't know if what to do, i tell him not to  worry so much at this age,(10) that he is too young to worry about earthquakes, tsunamies,hurricanes,and dieing at 21. somtimes,he can't sleep at night and there in the day he worries a lot and asks 1000 quetions to our family.   we love the fact that he loves science, we also know that the teacher is a science teacher and that is her jub to teach him about science, but to me i just don't want  my son to always be scared that somthing is going to happen where we live.idk, any advice??  thank u! don't think his teacher has the right to say he is gonna die by 21!!! geez where did this teacher learn her teaching skills!! tell your son that no-one knows whats gonna happen. yeh we all should take better care of the enviroment and stuff. i could get run over by a bus rather than get killed by an earthquake etc. no-one knows but no point worrying so much. enjoy life!
