You start paddling, scared and tired. You look back and see a huge explosion. Uh-Oh, a lot of people just died. Thankfully, you're not within the blast radius. The current is working against you, and the island is far away. You paddle until you can't feel your arms anymore. Man, that island is really far away. You can either stop paddling, and risk being stranded at sea, or keep paddling, and risk of dying from overexhaustion and overworking your body.
