extreme sport

Really extreme sports are not of much importance or of much interest to me, and I don´t know much about them.I know only a few,I saw them on TV, such as surfing, diving and motorcycle racing in the snow.In the tv saw motorcycle racing in the snow, where a man exposed himself to danger and with the noise of the bike was unleashed an avalanche and the man was trapped under the snow for three minutes!!

that's why I do not like that kind of sports
