Modern means of communication are changing every time. They influence our life immensely. If many centuries ago people did not know about them, nowadays we cannot imagine our life without them. Among modern means of communication, my most favourite are a cell phone and the Internet. I talk to my family and friends on phone every day and it is very comfortable. As for the Internet, virtual communication makes it easier to make friends. But, of course, means of communication are very harmful for our health. People are so addicted to them that they don't pay attention to the risk. I think that modern means of communication are harmful but, if to use them carefully, you can possibly avoid it.

The tiger is the largest cat species, reaching a total body length of up to 3.3 metres and weighing up to 306 kg. Their most recognizable feature is a pattern of dark vertical stripes on reddish-orange fur with lighter underparts. They have exceptionally stout teeth, and their canines are the longest among living felids, with a crown height of up to 74.5 mm.They are territorial and generally solitary but social animals, often requiring large contiguous areas of habitat that support their prey requirements. This, coupled with the fact that they are indigenous to some of the more densely populated places on earth, has caused significant conflicts with humans. In zoos, tigers have live for 20 to 26 years, which also seems to be their longevity in the wild.
