Men In Island

This man was so excited to go on a voyage along with his close friends and relatives. They were all having a great time in the sea but a sudden storm took them by surprise and the ship on which they were travelling toppled. The man was knocked unconscious and later when he opened his eyes he found himself on the island where there were no other human beings. He feels lucky that he is still alive but he is very sad that he is left stranded on the island. Imagine that you are the man; could you have escaped?
