Research teaches you the weirdest things

At one of our meetings recently we discussed the factual side of fiction ie even if the event is made up if you don't have your facts straight you could turn off some readers.So I've just spent most of my time online today researching amongst other things water heaters, yes water heaters. I could tell you the number for the nearest corgi installer with my eyes shut. I now know far too much about gas water heaters I could probably troubleshoot any problems in ours. I know why the tank doesn't smell funny, how to relight a pilot light and that the gas I researched yesterday is not only highly toxic but highly flammable (dammit!!) and therefore wouldn't work in the context I was using it in.
