Can we change how our genes act? Do genes influence behavior and personality? Does the environment actually change our genes? We tackle these topics and more with professor of microbiology Dr. Bill Sullivan, author of the book Pleased to Meet Me.
We also cover epigenetics, gene editing, methylation and the microbiome. Bill tells us how our socio-economic position affects our genes, how DNA is getting tweaked in the womb, and how dopamine affects eating and alcohol use.
Plus – find out what Iceland is doing to combat violence, how our bacteria affects our happiness, and how the brains of conservatives and liberals are different!
