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

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."
