A decade after being divorced, a man in England is diagnosed with Cystic Fibrosis. Among other things this means that he has been infertile for his entire life.

He texted his ex-wife and told her what had happened and then said "Obviously something has gone on. And if you are honest about it with me I don't intend to sue you and you can decide how you want to tell the boys."
