How influenced are you by marketing tactics?

When I was in the States again last year there were a phenomenal amount of ads for pharmaceuticals in particular. The question is not, however, limited to those types of ads. Did you actually show enough interest to purchase a product you might not otherwise have, based on the marketing tactics used? Have you, as an example, had a few times when you didn’t have an erection, not many, but just had a few, and then after seeing that there was medication for it, actually go to your doctor asking for the medication, believing that it was necessary to never have an erectile issue?
