| Jun 7, 2011 at 9:07 | comment | added | Andrey | @jwenting I was slightly wrong. Cancer is primary reason for death of all rats. | |
| Jun 7, 2011 at 5:56 | comment | added | jwenting | @Andrey, the claimants here would just argue that the cancer in your pet rat was caused by humans... | |
| Apr 28, 2011 at 19:05 | comment | added | Lagerbaer | RE cancer, I think it's in the Neanderthal Museum in Germany that there are skulls on display that demonstrate that some stone age people performed brain surgery to remove a tumor. | |
| Mar 22, 2011 at 21:16 | comment | added | dm.skt | @Konrad: About life expectancy, one should consider that it was in general none different 2000 or 3000 years ago (in fact, it was much higher 2000-2500 years ago than 500-700 years ago). Eratosthenes lived 82 years, Socrates 72, Plato 80, Xenophon around 75(+/-1). One of the main reasons for having a low average life expectancy, apart from high child mortality, was that e.g. a Roman chopping off your head or a Hoplite driving a spear through your guts significantly impacts life expectancy. | |
| Mar 22, 2011 at 12:54 | comment | added | oosterwal | @Gabe, @Konrad Rudolph: This site has life expectancy figures for a subset of the American population from 1850-2004. It supports what Gabe says about the life expectancy of a newborn being much lower than that of a 10 year old. The table also shows a huge increase between 1850 and 2004 in all age groups. @Andrey: Your anecdote does not prove that cancer is not man-made. All pet rats are exposed to man-made carcinogens. Your story may support the premise that the prevalence of cancer is increasing due to human activity. | |

| Mar 22, 2011 at 12:12 | comment | added | Andrey | I would like to add that cancer (especially brain cancer) is dominant death cause of pet rats. I had one and it died from cancer and vet told me that almost all of them die from cancer. So one more example that cancer is not because of human. | |
| Mar 22, 2011 at 12:08 | comment | added | Konrad Rudolph | @Gabe Interesting, I had missed that. In fact, I’ll update the answer. | |
| Mar 22, 2011 at 12:05 | comment | added | Gabe | I read the same article: "a Roman Life Expectancy table at the University of Texas shows that at birth the life expectancy was 25 but if one lived to the age of 5 one's life expectancy jumped to 48." | |
| Mar 22, 2011 at 9:37 | comment | added | Konrad Rudolph | @Gabe Valid point. However, the Wikipedia section that I linked to also includes the (well-sourced) remark that “occurrence of older age became more common late in human evolution”. Furthermore, even taking child mortality into account one arrives at the same conclusion. For example, life expectancy increased drastically after the age of 21, at which point the person was already a full-grown adult. “infant” mortality is a bit misleading in this regard since it implies that children exclusively died shortly after birth. | |
| Mar 22, 2011 at 7:03 | comment | added | Gabe | While I largely agree with your conclusions, life expectancy was so low because infant mortality was so high. If somebody lived to be 5 years old, they'd probably live to be at least 40 or 50. | |
| Mar 21, 2011 at 21:30 | comment | added | Konrad Rudolph | @Stefano Diagnose bias was certainly present but people back then did know of cancer – see Ophir’s answer. | |
| Mar 21, 2011 at 20:54 | comment | added | Stefano Borini | Also, important to consider the diagnose bias. I'm quite sure nobody in ancient egypt knew what a cancer was and if someone died from it, they would have just assumed he was cursed or something. | |
