You are visiting your grandmother and notice that she is eating a balanced diet, taking vitamins, getting the proper amount of sleep and is not overweight. despite her healthy lifestyle, she appears run down and tired. you realize that it's due to her lack of physical activity. write a convincing letter to your grandma explaining the benefits of participating in regular physical activity.

Dear Grandma,I'm so glad you're eating right, but I'm concerned that you're not getting enough physical activity.  Without being physically active, your body can't function as well, even with all those vitamins you're taking!This is also the reason you've been so tired lately.  The less you do, the less you'll FEEL like doing.  I want you to get out more, maybe we can go places together, or even just take a walk around town.I enjoyed my visit yesterday, hope to see you soon!-(insert name here)

I hope this helps! :)

Avaccine? hiv preventing, of course.
