Day four. Again I slept well. No body aches or pains. Another relatively easy day today to acclimatise with a four hour uphill, downhill and flat track with small pebbles and rocks. And still that insidious dust. I can't even seem to scrub my knuckles clean. The weather is amazing but full sun is hot for trekking and copious quantities of sunscreen is needed everywhere. I am still trekking in a short sleeve top as I sweat, oops sorry perspire a lot (thanks Graham). Good to sweat as I don't need to pee so much considering I am drinking over two litres each day. We are at Moir camp at 3,980 metres. Not many camping here unlike other sites. We have actually skipped a camp and come to this one instead for acclimatising. It is definitely getting colder, however the evenings are magnificent. Clear shies, zillions of stars and a full moon. Our weather has been amazing. No rain and none predicted either.

Our after dinner game created great discussion. What would you have liked to have invented and why and what would you un-invent. Bed at 8pm and again it is pretty cold although we are only at 3890 metres. Around about 3 degrees I think.
