@EvilCartyen we are on the same page exactly, of similar demographic - and 105kg. I think I've recounted more than once on here the tale of when my friend went to sensitivity training and they asked the group if they were afraid to sleep in a first floor bedroom with the window open. He brought the question home to me as a test, and just like all the men in the class I had no idea what the problem might be - Was it too hot? Mosquitos?? ALL the women knew. And we need to, too.
