Many of my relatives lived to a ripe old age thanks to amazing genetics. However, My father died in 1979 of what we now think was an anneurysm. This was prior to the miracles of modern medical diagnostics. My two brothers also have anneurysms - one had an ascending aorta replacement and then extensive cardiac ablation for atrial fib. My other brother an anneurysm that has not advanced past 4.8 cm. Both have had prostrate cancer requiring surgery.
My maternal grandmother died from rheumatic fever in 1926 when my mother was not even 2 yrs. My mother's heart valves were damaged from the fever, but she received new valves and pacemaker in 1996 and now I hear they no longer have to open the chest and heart for every surgery. She lived many more fruitful years.
My ancestors were farmers and raised all their own food. It was healthy, flavorful and untainted. As organic as you can get. They were not plagued by many of today's health issues from poor eating habits. Obesity, diabetes, high blood pressure. Populations today are plagued with unhealthy eating habits leading to death and disease from over-eating junk food and just plain over-eating, We have GMO food, chemicals, artificial sweeteners, tasteless food, and so many fad diets that do not meet the human body's needs. Including meat, whole grains, fresh fruits and veggies grown naturally. And yes eggs - the whole protein. It is possible but costly to find "clean" meat.
The past was wholesome and much more simple in many ways, but definitely not without many health issues that were not treatable - diabetes being one of them. Life was not as easy as you think. Sorry.
