Can't stand the koyak singaporean weather lah. So irritatingly hot - and way too humid.
There's this idea of a comfort zone (below), beyond which work becomes inefficient. heh. justification for aircon. Luckily our classrooms got aircon (but cannot change temperature, sometimes dunno why too hot one).
I actually like colder temperatures. Around 12-22 (Hamburg) is pretty comfy, and -2 to 5 (Beijing winter) is refreshing (and not as cold as it seems). Aircon does wonders too :-)
