It all makes sense. Us Homo Sapiens should never have left Africa. We lost our body hair and developed lots of sweat glands in our tall lean bodies to keep us cool in that equatorial furnace. Check those Masai in Kenya.
Then we moved into Europe and Asia and beyond. The the lack of daylight meant we had to evolve lighter skin to get some Vit D , but then had to cover up with animal skins cos we were bloody freezing!! MS levels rise further you get away from the Equator too.
A species had evolved outside Africa that was much better to adapted to the cold , Neanderthals.
On a personal level , i never liked a warm home, i couldnt stand a too warm environment (even though Hypo), but now ive had to have a complete rethink. Im really starting to feel the cold, like never before. Its a real issue now. I start to feel nauseous with it as well. Hands and fingers cold.
The central heating is on for longer and thermo at a higher level. Double glazing is going to installed. electric blanket on all night, more clothing, etc etc. Sorry planet earth, regarding all that CO2, but i blame the ancestors.
