The most average ages that people die is between the ages of 78 and 86 years old.
Some people have less healthy lifestyles than others and some people die at age 60 to 68 years old and some live as long as 86 to as long as 100 years and sometimes longer.
But the average life expectancy at least in the USA is 78 years old but it doesn't mean that you'll die at that age but once you get to 70 and beyond it's possible that you could drop dead soon.
Still though as long as you remain active and exercise, eat healthy and get doctors checkups to ensure your health you may live into your 100's
My Grandma lived to be 115 years old and she was pretty healthy up until then and she remained active.
But some people do not make it past 70 years old.
