Up or Down?

Travelling is basically a destabilising activity, especially when 9 time zones & two climates are involved. Odd bouts of gloominess, sudden feelings of being too hot or too cold, stomach aches etc. are all part-and-parcel of long-haul flying and business trips. And that's before the lack of sleep, change in diet, general stress and everything else that all conspires together to make you ask the same question, at least three times a day, namely, "why am I doing this again?"

Even now, I look at that picture and have to reconstruct where I was, when, in order to answer the question of whether I was going up the escalator or down it. And it was only yesterday.
