warmup temperature weeks

today after warmup poses i only did sun salutations, padangustasana, padahastasana, sirsasana and savasana. i still have a cold with some coughing. a little heater busted and i replaced it. the temperature in the practice area is good. my mind was distracted with wondering how long is the visit by one of my flatmates' guest. i was told someone would be visiting during the Chinese New Year and thought it was for that duration of time. now it's two weeks into the visit.
