The world’s greatest chocolate eaters are the British

You should avoid chocolate if you suffer from migraines

Chocolate contains caffeine

There is evidence that chocolate is addictive

4.Everybody loves chocolate. A cup of cocoa before going to bed or a Mars bar on the bus – the British are obsessed with it. The average Briton eats 10kg of chocolate a year. Women eat far more chocolate than men, an amazing 67% of total chocolate consumption. And the most popular snack is KitKat – fifty are eaten every second in the UK. Chocoholics are people with a chocolate obsession. But are they addicts? Not according to recent research. This shows that chocolate is not as addictive as coffee – in fact，there is no proof that chocolate creates addiction at all. And it’s a lot better for you than we thought. Some scientists say that it releases the same chemicals that your body produces when you are in love. Now that can’t be a bad thing! Some more good news – it doesn’t raise your cholesterol level or give you acne, as people believe, and it can even be good for your teeth! It does, however, contain caffeine and is bad if you get headaches. So the least sensible time to eat it is at night. The British love chocolate but they are not as obsessed as the Swiss. The Swiss are officially the world’ greatest chocolate eaters – but then Swiss chocolate is the best!////////////////////////Women buy less chocolate than men

You are going to return on Sunday night

You will spend Sunday evening outside Lisbon

Cascais is popular with Portuguese people

On Saturday afternoon, you will visit an old part of the city

3.THURSDAY 18th June A Sunshine Tours rep will meet you at Lisbon airport and a coach will take you to your hotel. FRIDAY 19th June In the morning，we will take one of the city’s famous yellow trams up to the Castelo de São Jorge, with fabulous views over the city. The afternoon is free for you to explore the Baixa district with its interesting shops and cafés. In the evening, we will go to the Bairro Alto area for dinner and to hear the wonderfully melancholy fado music. SATURDAY 20th June A day of contrasts. In the morning, a trip to the oldest neighbourhood, Alfama. Its little cobbled streets are charming but it is also one of the poorest parts of the city. We will have lunch in the central Praça do Comércio and then take the metro to the modern Parque das Nações — the site of the Expo, which has some stunning architecture. In the evening, you are free to enjoy whatever part of the city you wish. SUNDAY 21st June A coach will take us out of the city to visit Sintra, summer residence of the kings of Portugal. Here, we will see the breathtaking Palácio Nacional and walk around Sintra’s beautiful woods and parks. On our way back, we will stop at Cascais, just half an hour from the capital. This is a real Portuguese beach resort, full of local people and crammed with restaurants, beach cafés and discos. After a relaxing dinner on the beach, the coach will take us back to the hotel. Our return flight leaves early on Monday morning./////////////////There is nothing organized on the Friday afternoon
