Is it o,k for 83 years old man to start drinking redwine.? does it have bad effect on urine system ?

Red wine: Studies vary on the positive and negative effects of alcohol but generally say that a moderate amount of wine is fine, i.e., one glass daily for females and two for men. Red wine is a bit more helpful than white in terms of health. Your dad's doctor will tell you if he has any medical conditions that make wine a poor choice then it sounds fine. Peace and good health.

No problem: There is some medical evidence that a glass of red wine might have healthful effects on your circulation and heart. If you enjoy this, go for it.
