Mysterious Island Swim for shore

You desperately dash towards the ocean. In a frenzy you dive into a breaking wave and begin clawing through the water screaking maniacally. The salt water pours down your throat as your screams sputter out. headless of the fact that there is no land in sight, you continue to swim into the blue void. As you swim, you begin to grow tired. You are getting sleepy. Wouldn't it just be easier to give up? Suddenly something smooth brushes past your leg. Its a shark! what do you do?


Do you?
