I asked the American sailors why they applied for the submarine

(1)Why would you want to go on a submarine when you always have to care about life-threatening situations like flooding
(2)I watched a lot of submarine movies since I was youngI kept thinking that the submarine was really cool
(3)It was wonderful that no one knew where they were sailing after such a long dive in the water
(4)It wasn’t natural for a submarine to go underwater. It was cool
(5)I wanted to do something challenging and something that other people couldn’t easily do
(6)If you go on a submarine, you’ll pay more
