Surf... I guess this is a good sport I always wanted to try it but I haven`t do this, but what is the good part of surf: it consists of sliding on the waves standing on a table, it can be risky due to physical exertion and possible injuries caused by not taking the necessary precautions... so the first thing why people do this is: "adrenaline" but it is like any sport so the important thing is to take care in all that you do and you would have a very joyful moment in any place or with anything you do... :)
