Air conditioning

A week away, seeing the sights, visiting friends and relatives. I've had a wonderful time.

On and off planes, in and out of different temperatures and buildings with and without air conditioning. My cold has almost gone, but the cough remains, encouraged, in my opinion, by the air con.

Three more flights now, two more destinations and then, with luck, the cold will have time to clear up. I did spend some time wondering if it was worse than it would have been before treatment, but I suspect not - air conditioning and recycled aircraft air have a lot to answer for, it seems to me.
