Sorry but as I stated in my original reply and contrary to subsequent posts, room temperature is generally considered to be 20 to 25 degrees centigrade - a comfortable temperature not 'warm'. All a matter of opinion I guess, if you live in the north perhaps 20 is quite warm but in most places it's the bottom end of room temperature... and 16 is definitely cold! Brrrr
I guess in Britain, not shivering is often quite a good result for our holiday temperature!
From Wikipedia: "Room temperature is a common term to denote a certain
temperature within enclosed space at which humans are accustomed. Room temperature is thus often indicated by general human comfort, with the common range of 20
°C (68
°F) to 25°C (77 °F), though
climate may acclimatize people to higher or lower temperatures".
