When I see things like this, it makes me really think to the root of who we are as people and how depression plays into our role as human beings. I often wish it was possible to provide a genetic &quot;vaccine&quot; to depression in early embryonic stages of human development. If there was some way to encourage growth of 5-HTT alleles (longer alleles equal less prone to depression) we could see people born seemingly &quot;immune&quot; to this state of being.
