I know life expectancy is not guaranteed. Some people just lived longer than others, but it seems like some kings lived more than double the average life expectancy of their time. Is there any reason to this? Were they just lucky or is there a historical reason for this?
I'll try to give an example. Let's say there's a king in 13th century England. He lives to be 80. The average life expectancy of that time was around 30-40 right? Why does it seem as if the kings lived longer? Were they protected more from disease and hunger because of spending time in the castle and not spending his entire life working in horrible conditions?
Life expectancy of 30-40 doesn't mean most people die at age 40. It just means a lot of infants, children, and women giving birth die and bringing down the average age of death. If you survived childhood and didn't die from childbirth or other hazardous things as a young person, you are likely to live to a relatively old age.
