As I had been married 10 years, I am worried about our future; I try not to have a child. I feel that I want to show my grandchild to old Father. But I also feel that it is awful to have a deformed child by any chance (very little possibility). When I think of it, I feel uneasy. So I control (practice birth control). Of course I am very sorry for my wife.
I heard that even A-bomb survivors have a normal and health baby. But I feel that if my polluted body and blood are handed down to my posterity, it is a puzzle to do so (I had better to think again).
