Finn: And finally, high blood pressure.
Rob: So blood flowing around your body at a higher pressure than is normal. That's dangerous. Well, sometimes drinking coffee does stop me sleeping and sometimes I feel very alert and then very lethargic – you know, that's not having any energy. But I still can’t give up!
Finn: And Rob, you're not alone. We asked people on our BBC Learning English Facebook page how they felt about coffee, and we had a lot of responses.
Rob: Yumiko says: “My happiest time is smelling coffee beans just after grinding it. Fresh roasted coffee has a really good fragrance!” Fragrance is a word usually associated with perfume – but I think she just means the good smell.
Finn: Samuele says: “One cup of good espresso is the daily energy for my body and mind”.
Rob: And Rasha claims: “A cup of coffee every day is useful for our health”.
Finn: Ahmed loves coffee too, but he says: “Be aware that too much coffee is not good for your health”. So there seem to be some good effects and some bad – or negative – effects of drinking coffee, Rob.
Rob: Well, I find that if I try to give up drinking coffee, I’ll also get headaches and feel tired.
Finn: And these are what we call withdrawal symptoms – the nasty physical and mental effects of stopping.
