2 things... firstly , is an old life worth less than a young one? I reckon it sure is worth less, but since we have the same old brain, we don't think this. ( I always thought that active 70 y/olds should get jobs as hit-men, on account of how they can't be punished so much. Alas, I changed my mind when I got to be 70...
Secondly, if there have been a lot of people on a ute without seatbelts, and they all died on a rollover, in my experience they are ( were) aborigines. I bet this statistic is not published though, who wants to be called a racist?
