My impression is that COVID is problematic because a lot of people spend weeks on the ICU. The death toll itself is not that big, but having ICUs overflowing is a bad thing.
ICUs were built to take care about acute problems and there is a silent expectation that most patients admitted into ICU care either die quickly or recover enough within 2-3 days to be transferred into regular care. Having people around on ventilators for weeks destroys logistics of ICU systems.
We put way more than zero research into anti-aging research. Granted, COVID attracted a lot more money and attention, but anti-aging research is gaining traction. And with the tech moguls of SV aging, you can bet on some extra investments.
I for one don't believe that people like Bezos (a notorious fitness and health fanatic) are just going to succumb to natural aging without a fight.
