Yeah, when I had colon cancer I got a couple of helium canisters for party balloons from Amazon, and a mask from the Hemlock Society. However, the chemo and radiation worked so I'm still here. I got rid of the stuff because I figured by the time I want to use them, they'd be unreliable anyway. I'm currently trying to cope with the idea that suffering has always existed. But it seems like people of good will should be able to form a society, worldwide, that minimises suffering. At least a hell of a lot better than we have.
