Hi, Annie. Thank you for your suggestion. Especially about exercising, my dad used to play golf, too. But he can't anymore. I guess it's too much for him. Moreover, we're in Thailand and the weather here is almost unbearable for playing such sports.

My dad is kinda upset now. He's been taking so many medicines and some causing insomnia. He's getting bored of seeing doctors (5 or 6 doctors by now), but I'll try to persuade him to see a physical therapist and a nutritionist as you suggested.

For your questions. My dad is 54 this year. Twenty years ago or so, a doctor said he had Hepatitis B virus. Though it isn't supposed to, the virus disappeared after a while. We thought he was lucky back then until he's diagnosed with cirrhosis, which is caused by the virus.

Again, thanks a lot for your suggestions! And sorry for my bad English, I'm not a competent English user.
