Not everyone who needs medical help for Covid-19 needs a ventilator. Some just need supplemental oxygen.
And people go to hospital with other conditions. If hospitals are 100% overwhelmed with Covid-19 cases, then they may struggle to treat strokes, heart attacks, car crash victims, cancer patients, etc...
It's a worrying thought. My dad has become much less empathetic and more bitter over the past decade. I'd assumed it might have been the pain that was at least partially responsible, now I'm wondering if its actually the painkillers
Iran's military has been very intelligently shaped to maximise its ability with limited resources against the threats it's most liable to face.
If Iran had focused on developing the best tank force or air force possible, would it make a difference? No, Iran's most likely enemies are either the US or a country supplied by the US and the best Iran could produce would still fall short. They would certainly lose a conventional war.
So Iran has focused on developing asymmetric warfare capabilities. Their very large infantry and special forces mean any invading force will have an extreme insurgency problem to deal with, which could keep any enemy bogged down in a bloody and expensive war for literally decades. And their ballistic missile force can target important economic, military command or political targets, adding another significant deterrence.
Yes it is totally supported by evolutionary algorithms. Traits that are harmful in some situations and beneficial in others can be passed on, like sickle cell anemia which gives a degree of protection against malaria. The same as traits which are beneficial to some of your offspring and advantageous to others, like a strong jaw. Which would probably look better on your sons than your daughter.
It can be evolutionary advantageous for some of your kids to come first, even if it means others come last, rather than all your kids coming second.
