Stephan:   I have come to see air travel as positively dangerous, not because of air flight, but because of the condition of the planes, their bathrooms, rugs, tables, the recycled air, and the seats. I have gotten sick several times after flying six or 18 hours sitting next to someone obviously unwell. This story confirms my concern. Wash your hands frequently, don't touch your face, raise or lower the toilet seat while holding a piece of towel or kleenex. Now I think I will wipe down the folding table with one of those antibacterial wipes.
