Viruses/Germs vs genes

A virus makes you fat?
A virus makes you autistic?
A germ makes you gay?
A germ makes you schizophrenic? (Remind me not to go near cats).
Maybe, maybe not, but viruses/germs are ubiquitous and genes are not the be all and end all.

Also I would like to take this opportunity to coin the word "germes" for foreign DNA/parasites that have effects that seem indistinguishable from genetic. For good measure, I also coin "germome", and "germetics", and "germealogy" (yes, that's how you spell it).

Start using these words immediately.
