Finn: I think they're all coffee-drinking countries but I’ll say b) Finland. 
Rob: OK. As always, I will let you know the answer at the end of the programme. OK Finn, I haven’t asked you yet if you drink coffee. So do you? 
Finn: I do Rob, yes, but only in moderation – so that means not too much. I love the taste and the smell especially – we could call that the aroma – but it's the caffeine contained in the drink that can have a bad effect. If I drink too much it can give me headaches. 
Rob: Right. Well, for me, it's the caffeine that keeps me awake. It stimulates my brain – it makes me more alert – that's why we call caffeine a stimulant. Caffeine can also be found in energy and cola drinks and even in tea.
