For decades, we have been told that our genetic code holds the "blueprint" to our health and our lives, so "choose your parents wisely".

However, we are now starting to find out that there is an extra layer of control over how genes are expressed, and that these changes in gene expression can be heritable.

Can what we think and how we live actually change who we are?  Can our experience today change the next generation? And what’s so epi about genetics, anyway?

Chris and Mike get very excited today as they run wild at the potential of the ways we can change our DNA, and ultimately the way Health Happens to all of us (see what we did there?).
