We have held forums here at the White House on workplace flexibility, and the first major bill signed into law by President Obama was the Lilly Ledbetter Fair Pay Act.

Epigenetics doesn't change the genetic code, it changes how that's read. Perfectly normal genes can result in cancer or death. Vice-versa, in the right environment, mutant genes won't be expressed.
