Winter just keeps hanging on

The last few days has given us a final taste of the Winter season.
Though we have not had it as difficult as some folks have, it seems like when ever this stuff happens it goes right to my lungs.

The heating inside the house causes the air to dry out. This makes the air passages drier, even though my Oxygen supply has a humidifier system on it. The result is that the lungs just don't work as efficiently so the air just seems harder to come by.

Walking from the front room to the back, perhaps 25 steps, or doing a simple task, and my pulse ox will be into the mid 70's. I had hoped that we were fairly well through the season, but guess it'll be here for a little bit longer.
