Anyone with any sort of science background (or even just common sense) would know that pure oygen is unnecessary, and even bad for you in large amounts. Hemoglobin in blood is nearly saturated after leaving the lungs (~97-98%) in normal air conditions. It can also be dangerous if you breath pure O2 for long periods of time, as it can cause pulmonary (lung) problems and can even turn you blind. This of course won't happen with the short use of those bottles but, again, its still useless. Your climbing example is pathetic at best. They are not used to the much lower atmospheric pressures at very high altitudes. Last time i checked, Montreal is nowhere near the elevation of Everest And as for being a troll...hmm i registered in 2001 and you...in 2005. And wouldn't a troll be defined as someone who posts dumb messages that are both false and intented only to provoke?

Troll or not, read the label on the oxia thing, it's not pure oxygen.
Secondly, no one likes you here. You should of left in 2001 when you noticed everyone hates you.
