When we visit the US, often there are TV adverts for prescription drugs which YOU are encouraged to ask your doctor about. Especially common are those for ED. Nice cosy middle aged or older couple, holding hands, walking on a beach with voice over about quality of life in later years.
Then comes the speed-reading side effects (like the T&C's you hear on adverts her read at 100mph)
The last one is always something like..... "If you experience an erection that lasts more than x hours when taking this drug, seek medical attention immediately!" If you are imagining the responses from viewers... you'd be ROFL. Yes it's dangerous, but the way they say it sounds so out of sync with other side effects, like blurred vision, etc.
