Most of my friends thought I would have trouble tolerating the heat and humidity in Asia given my old age and conditioning in San Francisco. It was dang cold (55F) in San Francisco the day we left. After three months of cold S.F. summmer, I was looking forward to these warmer climes for awhile. It has been 80 to 90F each day that we have been in Asia so far, with high humidity, and I am finding that I have accustomed to this well and even prefer it to the blast of extremely cold AC experienced inside the restaurants.
