A dialogue between you and your friend about the importance of physical exercise.

 Ruba     : Hi! Chaiti, How are you? What are you doing now?
Chaiti    : I'm taking physical exercise. Have you done it
                   in the morning today?
Ruba     :  No, I'm not fit for it because I'm very weak. So
                   I'm afraid of doing such kind of hard work.
Chaiti    : What do you mean? It's not a difficult task at
                   all. Do you know it is very necessary for all to
                   keep fit. It means just the movement of the limbs
                   of our body according to rules. You can play with
                   us, walk with us or alone, swim on water. There
                   are not difficult at all.
Ruba     : Doesn't it need strength? How can I get strength?
                  I keep sick always.
Chaiti    : Now, listen to me. You must take physical
                   exercise regularly. You should participate with
                   us to play outdoor and indoor games. If you do
                   these, you will feel strong.
Ruba      : But now can I get time for it?
Chaiti    : No matter. In the morning or in the afternoon
                   you can do it. Remember health in wealth. Only
                   study is not important to be happy. Regular
                   Physical exercise will remove your weakness and
                   diseases from your body.
Ruba      : Is it enough for me to be healthy?
Chaiti    : Yes, you should take also good food and keep neat
                  and clean.
Ruba      : Thank you Chaiti. I'm proud of you. I'm happy for
                   having such kind of friend like you.
Chaiti    : It's ok, you're welcome.
