I am in the middle of a 14-hour layover in Sao Paolo, between two ovenight flights (from Dulles and to Fortaleza). My only exercise has been pushing my luggage cart around the airport to get the lay of the land.
I picked up a travel guide to Brazil at Dulles. It says that under no circumstances should a woman travel alone in Brazil, if it can possibly be helped. It also talks about robberies and muggings in some detail. Like, a scout hangs around a taxi stand, identifies a vulnerable target (eg single female), radios ahead to motorcycle thugs, who pull the taxi over at gunpoint. It is recommended that I put my cash in my underwear. Yuk. So anyway, I decided not to leave the airport here in Sao Paolo. Anyway, I can not recheck my bags until just before the next flight, and it is cool and rainy outside. Instead I reviewed a paper on using multiple species' gene expression data to improve the identification of previously unknown genes in a biological pathway. bleah.
Since I am feeling edgy anyway, I will share this Random Swiss Matterhorn photo of the day, sighted at an apothecary on Zermatt's Bahnhofstrasse:
