A: There is some scientific evidence that a small amount of red wine will help reduce the chances of cardiovascular disease.
A small amount.
A glass a day.
Nowhere in the research does it suggest creating a red-wine IV will eliminate heart disease altogether.

If you insist on trying to save her with your unproven, fictional, "scientific" method, at least use actual red wine, and not a homemade mixture of Everclear and Fanta.
