He says that if he could live a longer life in good health, he'd gladly do it. However, he says that people are not meant to live in pain like that, and he doesn't want his life to be extended just so he can be alive and be sick. He's happy with what his kids are doing, and he wants all of us to keep going, keep it together.
This is a very painful thing for me. However, while I'm not one to believe that all things happen for a reason, I don't plan on giving up. My dad is a very strong person, and he never taught us to do that. We'll be fine. Let's just hope that those three months turn out to be much longer.
