Atherosclerosis in mummies....
From the article :
"A study in The Lancet of 137 mummies up to 4,000 years old found a third had signs of atherosclerosis.
Most people associate the disease, which leads to heart attacks and strokes, with modern lifestyle factors such as smoking and obesity."
According to wiki :
The practice may have begun as early as 5000–3000 BC (up to 7000 years ago)
Mummies are associated with the very rich of the time - perhaps bodies of poor people were buried/burned or possibly even some were mummified as best as they could afford ( so not long lasting)
The long lasting mummies found today were probably the very rich as it would have been costly to get such a long lasting job done.
These rich people could afford all the luxuries of life (no physical work or exercise, very limited sun exposure, eat too much tasty but bad foods, sitting a lot, overweight, no fasting, smoking tobacco and/or other natural drugs of the day etc etc).
If true then we are just seeing diseases of the very rich lifestyles of the day (of few 'lucky ones' ).
