And they’d keep.
We had 3 days of record temperatures of 40.3 °C (104.5 °F) last year and that was shit, no sleep, no Air-con, no thanks.
I remember -14c in the early 80’s, getting snowed in our village and that was infinitely preferable to the heat last year, I have three fireplaces that I haven’t used since the double glazing went in about 5 years back so there is that option.
There is a genetic factor, I’m sure, my ancestors undeniably fled north to escape the heat, when my wife drags me to the Med’ every couple of years, I love the places but hate the temperature, as global warming kicks in I may have to move to Iceland.
