There often isn't data for older age groups with the studies accepting only up to age 55 or 60.
It varies a lot by country and is generationally changing such that today's 30 year olds will have a lower incidence at age 65 than the current cohort.
I think its a safe assumption that over half the population alive today will become infected before they die, excluding a vaccine being released.
Yes but that is for all age groups. I was wondering if there were data for people in the age group older than 50? Have you run it this quote I have put a link to?
It is more like 60% or so, but yes it is that high a proportion of people that will be infected and for most it is no issue at all.
You may already be infected from your youth and not know it.
