Maybe someone can comment on why every hospital I've ever been in seems to have a flaky electrical system. Lights flicker and dim seemingly-randomly, like someone's respirator in a totally different wing has somehow dimmed the whole building. There are clicks and clacks everywhere as if every light fixture has four relays buried in it, and the flourescent lights, even when they're not blinking out, have a constant flicker to them.
I've seen this in three hospitals, and never in any other type of building. :P
