Good morning my dear
how can we keep ploy warm?
She could use a cover from her bed to wrap around her.
The best way is to use thin layers of clothing perhaps 3 or 4 on top as this will trap air between them which the body heats up and then she will feel warm again.
or she could exercise to keep warm and no shorts. jeans or trousers she should wear also.
I am happy about the maths i have some more which i can send you.
it's very cold here now it's 5 degrees
please take great care for me
hugs kiss
your keith
