Dear Michael,
Thank you for your recent letter. It is so wonderful to hear from you! You asked me about what I do in order to live a long life. So, I want to tell you about it.
The first thing I do - don't look back and live for today. The past not return, and the future we don't know. So why not be happy today?
The second thing is to do your favourite activities and Hobbies. Enjoy sports and healthy food.
Tell me, what are you doing in order to live a long life?
Im sorry, I have to go to the sports section.
   All the best!
