After having my first child (a girl who is now nearly 3 years old) these stats impact me so much more. My first roll was a girl in the Iraniam plateau in the 18 century who had a 33% chance of dying before they reached 5. She managed to live to 70 but experience so much death in her life.

I can't imagine my daughter dying before she reaches 5, it feels like it would be the worst feeling I could possibly imagine and then some.

Visit any older cemetery and look for the tiny headstones and the matching very brief lifespans, or read an older obituary for someone from your great-grandparent's generation or further back, or watch a couple of seasons of _Call the Midwife_.
