Dear WW: Quite a bit of exaggeration there. The condition, which I learned as "phlebothrombosis" fifty
;years ago is far from new. My mother's mother died of it from being kept in bed a month after delivery.
I think it was first recognized by Dr. Michael DeBakey in early l940s. The airline passengers are immobilized
far worse than anybody with a sensible chair at computer can get up and stretch far more easily and
effective than the human sardines on some airline flights. I walk three miles a day, and sit in front of
my computer all the rest of the day.No clots in my legs.
