LOL. I guess its a better way to go than David Carradine. BTW, the lake in africa was Lake Nyos, a really deep crater lake. It was a pretty tragic story about the power of CO2 over aerobic life.
Our brains are really funny how they respond to O2 and CO2. For instance, the desire and force that drives us to want to take a breath is not driven in response to low O2 concentrations in your blood; its high amounts of CO2 that is the chemical signal. Like when you are diving in a pool and you get the "signal" to surface and breathe, thats your brain telling you there is too much CO2 in your blood. But you only "pass out" when your blood O2 levels drop. So it might be a rare instance that by breathing a huge amount of CO2, you will pass out, because your brain will only pass out when your O2 sats drop. But that does not mean that it wont jolt your brain and other senses! And, man, it does! What a great and unique experience.
