Gina aways feels tired because she likes watch TV. So my advice is she should go to bed early and she shouldn't watch too much TV so that she can get enough sleep and she will feel energetic next day. Tony is stressed out easily so he should listen to some music. Such as classical and pop music which can make his relaxed. She shouldn't study too late. Julie is a bit fat so she should take more exercise and she shouldn't eat too much meat and junk food.
