I also had this set up in my mind that people want to be Hero's so they stay at sea or become volunteers just to help people. I think every lay man would say this but here you given us the other perspective and the most genuine one because these people simply love the sea, they are swimmers and their mind n soul even their hearts, it's with sea. As I say do where your Heart belongs.. Again a work where lot of dare, bravery and courage is needed. One more courageous post :)
