BBC News - Carry on camping - can a week under canvas reset our body clocks?.
Well I think I kind of knew this. The last time I had a week or more camping was before going to Polanyi's lab in Canada (and also just before getting married). I found that it took about a week to get into the camping groove and forget about home worries, also about a week to relax and just enjoy the walking, (minimal) chatting and walking.
NB: My tent's a Terra Nova (not pictured)
