One of the things I like to do in my free time is to dig up interesting documentaries to watch on youtube (especially scary ghost ones).  I found this interesting documentary (don’t worry, it’s not scary) regarding how the environment affects our genes which are then passed down to future generations.  The lesson of the story?  Take care of your genes, at least until you are finished making babies.
