Every ad that we see makes an imprint in our brain. It uses our own brain resources to store itself in memory, in the connections between our own neurons, because that's what our brains naturally do.
Who knows, it might even be consolidated in there and compete with actual, useful memories of our real lives.. Biasing the competition in their favour, ads are designed to attract our attention and stick in our memory as much as possible.

Like cigarettes rot our lungs, it's very likely ads rot our brains.. We should protect ourselves from them and set up boundaries while we can!
