Dear Dad,
I have seen recent health issues, and I think you need to do something about it. Maybe try eating healthier, or exercise. Just stop making things worse by sitting there and doing nothing. Also, I think if you also go to the doctor they can check up on you, and give you more of a descriptive pattern of healthy things to follow. I am very concerned for you, and I only have best interest for you in heart. Dad if you could please listen to my instructions, I don't want to see you get worse. Please, get some sleep, and do not work yourself to hard, it should help. While you are at it, stop drinking and going out late. I am afraid that you could get into a car crash when you are not in the right mindset. That would be great, and it should help your health.
Your son,
Josh
