My father is going to die before my mom.

I've never thought that my father would outlive my mother. He's always had medical issues and he drinks a lot. My mom has always looked after him. Less than a month ago, my mother got diagnosed with Brain Cancer, and is not expected to live more than a year. She never smoked a day in her life. My father is taking this very hard, and I just know he won't outlive her for more than a few months.<br><br>Edit: I'm sorry for not making it very clear. It's just that I'm upset about her condition and it doesn't help that I know my father won't be around for long after that. He's an alcoholic.
