Yeah, yeah, you can hope what you want. Normally intelligent people do not take preventive medicine for something they might be afraid to get. For that reason we have something called health supplements and a healthy diet as well as proper exercise. FYI, aspirin is not classified as a health supplement. It is a medicine.
Just to get it all straight:
Medicine is prescribed or taken for a symptom or an active illness.
Health supplement, healthy diet and exercise is used as preventive products.
There is no such thing as preventive medicine. If so, it is prescribed by a doctor based on an existing condition. If doctors recommend aspirin to people without ant existing conditions, they are committing malpractise which is to be seen as serious negligence.
