Lived in a hot climate, no. Visited for 3+ months, yes – Australia (Darwin, Sydney, Melborne and, usually, Canberra. He loves Canberra), Singapore, K.L., Oman. All air conditioned cars from ‘plane to hotel to office to restaurants, of course. He didn’t much like the climate in Singapore, and neither did my sister when she went, separately, a few years ago. Humidity has a while new dimension over there. She did love South Korea, though. Got to take a stroll through the N.Z., too, as part of her job.
