Here in the Netherlands up untill the age of 29 a whopping 7 people out of 11.500 died. If they had other illnesses i dont know but ye.. thats 0.06% of all deaths, 0.00086% of all 813.000 reported cases

Some other fun facts about the netherlands:

Total pop: 17.4 mio

Casualties below 70: 1127

Casualties below 65: 595

Casualties below 60: 327

Casualties below 70 with underlying conditions: 735 / 65.2%

Casualties below 70 without underlying conditions: 111 / 9.8%

Casualties below 70 undetermined: 281 / 24.9%

So out of all 11500 reported casualties that's 0.13% of healthy people that died below 70, half of which are between 65-69, (assuming the 111 registered cases)

Pop below 70: 15.9 mio

if all people would be infected that would give us 2060 healthy casualties below 70 based on the registered cases, here i am making a rough assumption that we tested 25% of all cases (honestly i think im being generous here) so that would boil down to 515 healthy people passing below 70, 260 people below the age of 65.
