While people are generally discussing their discomfort with using the tube I'd just like to chip in my main concern with it being around 50 Celcius constantly year round down there.... (yes, I exaggerate slightly, but not by much!)

My main concern is my extreme paranoia for having 'something like that' walk on me/in the bed while sleeping, Uhh...Brrr!

Having lived in black widow country as a youth, I have the same freak-out-at-crawly-while-sleeping syndrome.

side note: do not watch the video in the article if spiders freak you out

Yes. But O(2N) = O(N) :D

cheers :) (I changed the title completely)
