Apatient says to the nurse, "i have been drinking four glasses of whiskey daily for the past 20 years, and i never had any problems. i don’t know why my primary healthcare provider has asked me to stop drinking." how should the nurse paraphrase this statement?

If I was the nurse I would say

“ your primary healthcare provider has most likely asked you to stop drinking because while it might not have caused a problem yet the effect of drinking 4 glasses of whiskey a day for 20+ years add up over time and could cause serious health issues in the future”
