well basically man doesn't remember anything. so focused on swimming
he lost track of his life.
but even though this man has problems especialy personal problems such
as being an alcoholic that he turns to somehting he can try to forget
or do so he can become successful like swimming. i can't tell if he
uses swimming to run away from his troubles or just swimming to
improve himself in life by trying to prove to others he can be a
better person or to prove to himself he can change
