English composition about parents' health

Dear father (mother),

You are busy every day, so you don't pay much attention to your health. I'm worried about you. I hope you can keep healthy. You often drive to your office. It's not far. How about going there for a walk, because it can make you stronger. From Joozone.com. I hope you go to the gym to play basketball or swim at least once a week. It is important to eat healthy food, such as vegetables, meat, eggs and fruits. Although your work is hard, I still hope you can go to bed early so that you can get enough sleep.

I look forward to hearing from you.

Your dear son (daughter)

Tom (Mary)
