Teaching granny to suck eggs

From today’s DT
Moulton Medical Centre near Spalding, in Lincolnshire – where temperatures are expected to drop to -3C tomorrow – told patients “pull your sleeves down” and “wear socks” to stay warm.

Its guidance read: “If you’re sat down, keep your feet up on a stool – hot air rises, so floor level is likely to be the coldest part of a room. If you’re at home, try and move your legs around to keep blood circulating to your feet .”

It also said “avoid having bare feet” and wear gloves that are “the right fit “

Socks and gloves? Whoulda thought of that?
Harmless maybe, but somebody is presumably being PAID to utter these pearls of wisdom.
How much might we claim for our own suggestions?
I’ll go first - a thermos of soup to hand, and wear an extra woolly or two- real wool if you can.Thermal underwear, leggings or tights under trousers.
If all else fails, a greyhound snuggled into the small of your back or draped across your lap . (Other breeds and domestic animals, eg cats, are available)
