How to save a life - Swimming Story

A Doctor entered in the boat to travel and reach the far island. An Engineer also entered it followed by. There were very few people or traveler who came to the boat for the same reason. The wait is over and the boatman has to drive it from one place to the other island through the usual way.

The uneducated and poor boatman knows only how to drive it from one place to the other and earn few amounts daily from the travelers on this natural travel. The boat was reasonable with motor drive for a long distance.

The story in the sea:

A Doctor was looking at the scene around upon boat running and interested to know more about the atmosphere. Thus, he approached the boatman to know the safety precaution etc. he then explained about life jacket and all. 

He enquired extra about it. In that situation, the engineer also came in and interested to enquire a bit about design of the boat and maintenance etc. there is a reason naturally.

The boatman patiently replied for everything they asked for while driving even by attentive on his driving beside though it was like a humor around. The climate slowly changed after an hour. 

Just for a fun, the Doctor asked the boatman about his education. He replied, neither been to school nor studied. Doctor replied as, 'you wasted your one fourth life'.

The Engineer asked the next, any trade education?, the boatman replied, no. Engineer replied as, 'you wasted your half life'.

The boatman kept silent on these questions and weather changes from good to very bad at the moment, which boat can be in trouble or drown anytime soon. 

The boatman then asked these two (Doctor and Engineer by profession) whether they know how to swim? They said no. But boatman knows it and can face the drown and get a second chance in case.

The boatman replied to them, 'both of you wasted your whole life now'. 

Tips: Learning swimming is not very important but important to fight with water or nature sometime to save yourself.
