Hearing the same thing over and over

This is going to be a short and to the point comment. I keep hearing the same tired old advertisements urging us to use the latest and best medications or drugs. How is it that hearing the same old line over and over will convince me to purchase their product? Today it was Boniva, now I do not know it could be a very good product, but what is said in these convince me it is not worth the chance. Now its Plavix its supposed to reduce cholesterol plates building up, but the ad tells me not to try it because it could be dangerous. The straw that makes me made is that I am supposed to tell my doctor about this product, but be sure to tell her what she already knows. I prefer to let my doctor tell me what is best for given my health needs. Forget trying to sell their products for me to my doctor.
