   	This apartment building in San Francisco was constructed before WW I   
   so has no insulation.  Most of the time it is not missed.  When I miss   
   it too   
   much I apply my local insulation or go back to bed.   
   	There is a problem this year in that I cannot find my jacket liner.   
   	A sweatshirt helps a lot but that liner was warmer and had pockets.
