(Tarma, from a postcard)

My headache was getting worse and worse since we had passed Ticlio, 4818m and when we eventually arrived in Tarma, I had very severe pain.  It was the altitude sickness.  When I went to both Mt Oku-Hodaka-dake (3190m 10466f) and Mt Kita-dake (3192m 10472f) in Japan, I was fine.  I wondered why it was.  Maybe it was because I climbed step by step and gained the height by myself.  Then why didn’t I have headache when I went to the mountains in Switzerland? 

I didn’t know the reason, however, this headache was so severe.  It seemed a right decision not to have breakfast now.
