Joke about the ageing

   Two mature men talk about the ageing and one of them says to the other one:
   -" The worst part is for our wives, besides they don´t accept that they age and always try to hide their ailments."
   -" You´re right, but I have found a good trick in order to they realise their disabilities throughout a simple game. So, if you want to know whether your wife starts to go deaf, put yoursellf to 10 metres from her and ask her one question. Then, when you see that she doesn´t answer you, approach to her 5 metres. Next, to 2 metres and then, to 1 metre. And... in this moment, she will have to recognise that she´s keeping deaf."
   The other man thinks it´s a good idea and when he comes back to his home, he puts to 10 metres from her and asks her with a loud voice:
   - "My dear, what is there for dinner?"
   He doesn´t receive any answer.
   Then, he puts to 5 metres from her and asks her again:
   - "My dear, what is there for dinner?"
   He doesn´t receive any answer either, so he decides to approach to 2 metres from her and asks her again:
   -"My dear, what is there for dinner?"
   He goes on without receiving any answer.
   The guy, funny for the functioning of  his friend´ trick, approaches almost 1 metre and shouts:
   -" My dear, what is there for dinner?"
    His wife turns and says to him, close to breaking point:
   -"I´m going to say it for fourth time, idiot: soup and croquettes!!!
