The Circadian Rhythm The circadian rhythm is a kind of body-clock which regulates our body functions such as sleepiness, body temperature, hunger and alertness. Plants and animals have a circadian rhythm as well. Our body relies on the predictable cycle of light end dark to synchronise our body-clock. Therefore jet-lag breaks down our circadian rhythm because we loose the cycle mentioned before, causing tirediness and sleep problems. It's interesting to note that our clock oscillates at its own endogenous period, even if we were put into a dark cave. In addition, exercise, food and caffeine can modulate our sleep pattern, although they are not as strongly as the light and dark cycle. In conclusion, adjusting the circadian rhythm correctly makes us feel better, avoiding sleep problem.

A sweet topic A lot of news these days say that we are eating too much sugars. These are sometimes hidden in processed foods ( such as yoghurt,low-fat snacks and fruit drinks) that we think of as healthy. Another difficulty is to understand the information on the label, because we don't know how much is a certain thing. Fortunately, a lot of products have a colour coding on the packaging which helps you understand at a glance the information: red for high level of sugar while green for low level. On the other hand, it's wrong to demonise an individual nutrient avoiding it at all costs. Everybody should have a balanced diet. Therefore, cutting out a type of food, whether it's sugar or fat, is wrong. I definetely agree with it: I have a sweet tooth!

Watching an opera Last year I watched the opera Rigoletto by Verdi. It was well worth watching it! It was stunning and breathtaking! I liked the way the players sang and how they were dressed. For me the highlight was the sounds, you could hear everything really well. The opera was a bit long for my liking but in the end It really lived up my expectations! I would reccomend this show to anybody not convinced by opera.
