>>636032this and Tumo meditation.
How else do you think those Tibetans survive in the Himalayas?
Or maybe its just because they consume insane amounts of milk and butter wich is why they all have a layer of fat for cold resistance.
The are aren't fat tough, the long hikes and hard work in the mountains keeps them healty, muscular and strong.
I read somewhere that some people are genetically just more resistant to cold then other people so you might just be unlucky.
Post your e-mail or make an IRC channel and I will teach you Tummo (Inner Heat) meditation.
