I recall walking around a cemetery with my parents as a young child; it seemed to me that the majority had died before reaching 70 and many before reaching 60.
Life expectancy has risen - but as you question, will this trend continue.
A few observations come to mind.
In a class of 24 in my final school year there was only one overweight kid.
We all, without exception, played sport at school, and the vast majority got an opportunity to represent the school at some level.
Sport was more about taking part than winning - although we tried to win.
The vast majority walked or cycled to school - I did so when I was 6.
We had to be threatened to get us to go indoors - not to go outdoors.
Drinking soda drinks was a rare treat, not an everyday occurrence.
Our pocket money could only pay for a minimal amount of junk food - in any case there were more important things to spend money on.
Milk had to be consumed within a day or two of purchase - otherwise it went off. The same applied to bread.
There was always fruit available and no constraints on how much we consumed.
Water was a recognised drink to quench a thirst.
I could go on, but that's enough.
Medically we may be better off, but in terms of lifestyle that favours health , I think we have gone backwards.
