Ask and answer

I create this page to ask and answer questions not related to posts presented in blog. You may ask any question provided that it is written by English. The questions may be various: study, puzzels, games... Besides, you can also answer the questions given by me or others. However, you should use English. Why? Because I think that it is useful for you and for me to improve our English.

I strongly believe that this topic will become more and more interesting in the future. Now, let's solve the first three questions.

Question 1: What comes twice in a moment, once in a minute and never in a hundred years?

Question 2: When I eat, I live but when I drink, I die. What am I?

Question 3: What goes up but never comes down?
