Rick Thompson has uploaded an episode which covers some of the key vocabulary relating to this issue. The idea is that getting specific teaching from me and then just listening to a conversation about it, you'll be better equipped with the right language for your own conversations in Englishabout this topic. There's also another episode in the archive, by the way, which is all about vocabulary and phrasal verbs for feeling ill. And that is episode 40. When was that? At least 10 years ago but I think it's a good one.
