On the Bright Side I May Develop Super Powers
In the textbook Fundamentals of Anatomy and Physiology by Frederic H. Martini (now there's a man I'd like to drink) sixth edition, the first sentence on page 584 is, "An ordinary lightbulb or the sun emits photons of all wavelengths." This is not true. The sun is an enormous roiling fusion reaction in the sky and not even it emits photons of all wavelengths. An ordinary lightbulb certainly doesn't, or at least I hope it doesn't. The only light bulb that should be pumping out gamma rays is one on which Doctor Who has reversed the polarity of the neutron flow. Generally speaking, it is a bad idea to use things that emit high frequency photons as a light source without a decent plantary atmosphere between you and it on account of how ionizing radiation can kill you. And so ordinary light bulbs don't. That and the fact that a light bulb that puts out energy in wavelengths we can't see wouldn't be very efficient. That's why we got rid of ordinary incandescent bulbs in Australia. They put out too much energy in wavelengths we can't see, but that was short wave stuff, not cancer rays.
But at least this textbook isn't censored. One can freely look at people's guts without clothes getting in the way.
