Get an adrenalin rush with these extreme sports
A man dressed as Father Frost, the Russian equivalent to Santa Claus, makes a jump from a bridge across the Yenisei River in the Siberian city of Krasnoyarsk
Jump off the top of a very tall building with a packed parachute in tow and you're doing what is known as BASE jumping. Enthusiasts have jumped from buildings, antennas, spans (bridges) and earth (cliffs) - those who manage all four attain an exclusive BASE number to signify this. Venues to date have included El Capitan in Yosemite National Park (USA), the Burj Khalifa and even the Statue of Liberty.
