My dad is touching 56, he has been smoking since he was 25. Now he works at a pub and only comes home at 1 am and then gets up at latest being 7ish am. He is now pretty moody, tired and also changing a lot from the amount of attention he used to give to me. I'm so scared he will drop dead any second. Also he doesn't have a healthy diet that is nutritious. He just eats rice, some dal and meat. I want to help him in any way that I can. He wont stop smoking so I cant really do anything about that. Any advice on how I can keep him as healthy as I am able?
