My wife and I just recovered from Covid and had no problems with next to no symptoms (early to mid 70s in age). Others in our age group that also came down with it showed the need for steroids due to lung issues. All recovered nicely.
I would say Covid is extremely serious for those in my age group and nobody should take it lightly, but those of real concern should be those that also have secondary health issues and that brings just about all into the picture.
For middle age and younger, I don't see Covid as any more dangerous than the flu or pneumonia.
But that is just my take, no scientific data to back it up.
