You don't calculate how dangerous something is by what percentage of the entire population dies from it. By that reasoning, sticking your fingers in a plug socket or running across a motor-way isn't that dangerous, because a teeny tiny fraction of people die from it.
Death rates are based on people taking part, or infected in the case of the virus. That's why we can decide that certain sports, activities and jobs are more dangerous than others even if only a small number do them, and that certain diseases and infections are more concerning.
I find the dismissive hand-waving away of "oh, they had pre-existing conditions" as though it's OK very troubling. Those were all people. Someone's family member, a husband, wife, parent, grandfather, child ... because it isn't just people with pre-existing conditions, it can be anyone - it's not an absolute guarantee of safety to be young and fit and won't be if hospitals are overwhelmed.
Just because some government body declares something, why are we suddenly like sheep, trusting them implicitly. Government bodies declared that there were weapons of mass destruction and led us into a decades long war. Government bodies tell us all kinds of lies regularly.
I don't understand the rush to believe something so quickly that has hardly been investigated - the results are still coming in, they are guessing and it's reckless to proclaim the results while the pandemic is still developing and spreading.
