Jack, bad circulation all my life Raynaud's etc, but what is worse is cold raw and wet. Below freezing things feel much drier and the joints don't suffer. As far as warmth goes, 20°C and above I like.
I have the same problem with the Wife, must be a woman thing :-)
We have a country park walking distance from our house and we love doing the hour and half walk any time of the year, I can't remember when I last did it in crisp powder snow, but the weather ain't like what it used to be back then :-)
Anyway, both my anemometers are telling me the wind is now from the east, albeit 1mph.
