I only experienced snow, and that was light snowfall, a few times in my life.
I don't now if I will survive that type of weather. In cities where I stayed it get to -8 deg Celcius in winter, but it hardly ever snow.
The last 9 years we are living at the East Coast of South Africa, with sub-tropical weather. Not really cold winters.
Glad you had your warm clothes and that your house is "cold proof" with the under floor heating.
Take care in that cold weather.
