The typical human has the same amount of plastic in their brain as there is in a credit card as a result of the relatively newly ubiquitous presence of plastic nanoparticles in our environment.
Frankly I'd be shocked if jamming a credit card into a human brain wouldn't cause some measurable difference to how the brain operates.
Edit: I guess the specific reference of a credit card is still undergoing peer review! There are many published papers showing polystyrene in the frontal cortex, though.
That is not true (link is in Dutch, here it is Google translated)
That link says we don't EAT that much plastic per week.

This is saying that our brains are at this point 0.5% plastic by weight.
