And I replied:

  And much worse things can happen if your tiny grey cells are on vacation:

  A nurse in one hospital thaught that she could gain some sun-tan under the
  germicidal  lamp,  so  she  went  to  a room where some of the laundry was
  stored  and  layed  down for about half hour, intremittantly observing the
  'not  so  intense'  blue light which in fact is almost pure UV-C (peak for
  germicidal lamps is arround 237nm - ideal for UV-EPROM erasing).
  She  was severe burnt and her staring to the lamp gaved her 60% sight loss
  (permanent).
