Air conditioned cublicles don't count....and you also have been in the middle of a giant campfire for a while now
The solar light on my flag pole craps out after an hour or so on a typical winter day. Good thing I've got low voltage lights hooked up to my outdoor outlet also so I've got that light all night long.
Keep plenty of space around your space heater. After arson and smoking in bed, space heaters are a frequent cause of housefires.
