Default "Bone chilling" and "Bitterly cold"

I have every sympathy for the tree surgeon who has just been working in
my garden.
Temperature is indeed +5, but that wind (and low humidity) makes it
feel very unpleasant indeed.

I do remember the winter of 1963 and just about 1947. It might not be
numerically as cold today, but sure as dammit, it feels cold.

I reckon there is a fundamental omission in formulae which calculate
windchill temperatures. Here is the standard North American version (in
deg F of course)

Windchill (ºF) = 35.74 + 0.6215T - 35.75(V^0.16) + 0.4275T(V^0.16)

Whe T = Air Temperature (F)
V = Wind Speed (mph)
^ = raised to a power (exponential)

On the right hand side should a further negative, namely - 1.1269(Y^0.512)

where Y is years on this earth, or age:-)
