Someone told me recently that Buddhist monks can stay warm sitting naked in snow by meditation and breathing exercises. Apparently trainee monks have some competition to see how many tea towels they can dry out draped over their body whilst doing so...or something like that. Must learn how to do that, think how much weight you could save backpacking.
Sounds right to me, at least before I went to Italy and got my metabolism screwed up:-(
How did that happen?
Lack of anywhere half-decent I could get to walking or cycling without a very nasty road journey. Much more air pollution than here (due somewhat to a climate that doesn't dissipate it like ours). Consequence: too little exercise and body shutting down:-(
