A: "I haven't seen your father in like 5 years. How is he doing?"

B: "He's not doing too well."

A: "Why? What's wrong?"

B: "About a year ago, he started feeling weak all the time."

A: "Is it due to old age or is he sick."

B: "Maybe a little of both. The doctor's can't point out anything specifically. I think it is because he didn't take care of himself during his youth."

A: "That makes sense. It's important to take care of your health early in life."

B: "That's what my father tells me almost everyday."

A: "Well, I hope he starts feeling better. Say hi to him for me."

B: "Thanks. I'll let him know."
