 to make me a little better what I'm doing here over the years. But, John, can you explain why fentanyl kills? What does it do to the body? Narcan, you can resuscitate some of it. What does it do? Why are so many people overdosing? I'm not bringing this up because, you know, it used to be the god-awful images you would think is someone sticking a needle in their arm with that rubber wrap around it when they became a heroin addict.
