Which age group do the two speakers most likely belong to?

M: Hello. How are you today?
W: Not so good. My leg’s playing me up, awful pains in my leg and my toothache!
M: Oh, dear! I’ve got toothache too and the dentist says he simply can’t see me before next week. But what gets me is my headache.
W: I know what you mean, but at least you can do the garden. I can’t even do that with my back, the doctor says I mustn’t lift or bend.
M: You poor thing. There’s nothing worse than back trouble. But I don’t do much in the garden now because I’ve hurt my arm. It’s really painful.
W: Like my ankle. It’s all swollen up.
