A listening task

I have listened to two bbc listening tasks. One was about English people’s health and another was about drug addicts in United Kingdom.
I listened both for the first time and I understood everything, although I listened them both one more time, just in case I skipped an important information. Honestly, I haven’t finished listening the second task, because it was very long and it seemed that I really understood everything.
Both tasks were quiet long, but I really enjoyed listening about the first topic, because im very interested about health and nutrition. Speakers were talking about obesity among English people. Why is that happening? What are the main reasons? When did it start? Even 50% of all English people are overweight. A very interesting fact was mentioned, that in UK in 4 mile distance there are about 29 fast – food cafes. Fast food is cheaper, easier and faster to eat, and you can find it almost everywhere. People do not embark on doing exercises, the biggest their activity is to get in or get out of the car. Even those people, who go to the gym three times per week reward themselves for doing that with a big pizza or hamburger and few beers. If people will not pay attention to what and when they eat, the children will start to die earlier than their parents in 15 years. For me, a very interesting fact was that the government tries to help to suppress the obesity by banning the advertisements of fast – food or even putting extra classes in curriculum for children to learn how to cook healthy food.
The second listening task was about the bond between government and drug addicts. There are very many drug addicts in UK and the government tries to reduce the number of them by not punishing the addicts, but rewarding them. Firstly, they were rewarded by travels, but later on medical stuff started to reward addicts with another drugs, like antidepressants. The chief of this health section was not aware of this and there was a quarrel about that with a woman from this section and a speaker from the radio show. In addition, Britain is a leader in EU by helping and improving treatments for drug addicts, although the percentage of fully treated addicts in whole UK is not very big.
The conclusion is that if a listening task is interesting, so it is does not matter – is it long or short – the most important thing is that you listen it with a great interest and want to hear more. Although both tasks were more than 15 min, but I honestly wanted to hear more.
