This is just not true dude. Life people died in all age from all kind of curable issues.
Mortality of women during child birth is massively lower. That is the most apparently obvious one. Whole classes of diseases from malnutrition are down or don't exists or are fixable (anemia, lack of iodine, that sort of thing). Tuberculosis was frequent enough to have sanatorium specializing in that. Lepra.
When you read history of epidemics, of food and generally of medicine you find a lot of premature deaths that just don't happen now.
> Life people died in all age from all kind of curable issues.
Sure, absolutely. Just not in large enough numbers to drag the numbers down lower than today [after age 5], when we've dramatically increased the number of deaths due to preventable issues. For example, heart disease was much rarer, and cancer incidence was less than 10% of today's numbers. Fewer people died in car accidents, and fewer were shot by AR15s. The causes shifted around. We made medical progress, but we took steps back as well.
As I also mentioned, there've been peaks and troughs. As the paper I cited mentions, health became so bad after the mid-1800s peak, by the late 1800s and early 1900s, the British army had to lower its height requirements to absurd levels because of malnutrition - malnutrition that was a direct consequence of technological advancement!
