I don't know how much reading you've done already or how much science background you have, but if you have any questions about the subject or interpreting the info out there feel free to ask and I might be able to help. Epigenetics is a pretty hot topic right now, so there's quite a bit of misleading "pop science" and sensationalist nonsense going around, but there's also a lot of really good and interesting/exciting high quality work being done.
