Some things can be spoken, some can't
Speak your mind freely, but, one needs to have a little introspection to know that there is a limit to this statement. I would like to tell the world that I am a grad and my genes will produce another generation of grads. Please come and share my goodness. Telling this as a joke is acceptable. But telling this as a serious proposition is a no no. Why would people insist on saying such things? Sheer arrogance, or trying to tell the world of their good fortunes, that they are blessed? It can be a kind of conceit, or maybe deceit, that nature's endowment is forever, can be passed down through generations like monetary inheritance. Unfortunately, life or fate, has the habit of playing the most wicked jokes on human beans. When you think all is won, you can end up the loser. Or when all is lost, you may still come out the winner.
