i saw many relative slacklining reports on TV.
the slackers have a best sense of balance so they can walk on the
tightrope even which is shorter than one inch width.but i think they must spend a long time to exercise their slackining
skills and maneuvers to have a deeper this kind of sport ability.like the old saying that Rome is not built in one day.
besides, there are many and many extreme sports to enjoy for those who
want to have an exciting experience.so as i am young, why not to try them in my only life?
