There's also another important thing that you should take into account. Those statistics include all dead people who tested positive and died. It doesn't matter if they had last stage cancer at the time or were 90 years old, or were lying on intensive care prior to contracting the virus. If they tested positive and died, they're on the list, regardless of the cause of death.
Another important thing to note is that in the U.S., at least, if a hospital has a patient who dies of 'covid-19' then get an extra $12,000 or some such. That's a pretty big incentive to 'find' or 'suspect' covid-19, and suspecting it is all that it takes for a death to be labeled as such.
As a matter of fact, some entities would probably kill for a lot less than $12,000. Especially when you got some ancient oldster who is going to die pretty soon anyway. Perhaps that is why 'covid-19' is so hard on the very old? Hard to know. One way or another, the CDC has told doctors that it is 'unlikely' that they will be researching deaths labeled 'covid-19'. I guess they will be 'looking forward, not backward.'
