Back when Nancy Reagan was telling us to "Just Say No," this commercial was all over the airwaves:
About a decade later, we were subjected to "This Is Your Brain On Heroin":
Last week, President Obama announced a brain-research initiative. According to scientists who could be involved, this project is far more ambitious than the human genome project because, frankly, we know less about our brains now than we did about our genes three decades ago. Also, the genome project had a clearly-defined goal; by definition, such a thing is all but impossible in brain research.
Anyway, I'm waiting to find out what they might tell us about bicycling's effect on the brain. I'd love to see the commercial for that!
