Before the vaccination and modern medicine, we had a lifespan of 16 to 17 years.
I think world history would look a little different if it had been entirely forged by hormonal brats on the verge of carking it. Your figures might be a little off.
Yeah. Its off by about 15 years. But shockingly to some, life expectancy goes up with the birth of modern medicine. Widespread use of vaccines plays a huge role in this. Vaccinate your crotch goblins please.
