Swimming is one of the most tiring things .. Have you ever seen the shoulders of a swimmer? They are huge … and probably hands too. Yes, because the hands are nothing more than oars (or second fins) for those who swim. And often those who swim are even faster than those who simply row ..
Regarding environmentalism, the sea does not grant many alternative resources such as dry land, where electric motors or alternative vehicles are spreading, such as scooters and bikes. And so the greatness of those who swim is seen only from the competitive point of view and never from the environmental point of view … where they could spread green messages as you do on the streets ..
