If this disease kills old people mostly, what if we could make them younger, at the cost of some salt water and a low cost medical intervention?
You know how people were donating convalescent plasma? Turns out that plasma is worthless for treating Covid, but dumping it might make us age backwards.
Human attempt:
Today's news from the self-experimentation community notes a more adventurous effort, in which a few volunteers underwent blood plasma dilution followed by assessments of function. Plasma dilution, or neutral blood exchange, involves extracting blood, replacing the plasma fraction of that blood...

In lab rats:
Our recent study has established that young blood factors are not causal, nor necessary, for the systemic rejuvenation of mammalian tissues. Instead, a procedure referred to as neutral blood exchange (NBE) that resets signaling milieu to a pro-regenerative state through dilution of old plasma...

This all got started when an experiment was done by connecting the circulations of a young rat to an old rat, causing the young one to age faster, and to reverse ageing in the old one.
The cause was first thought to be some unknown elixir of youth in young blood. They looked for years, no luck.
Well it was the opposite. It's the elixir of age in plasma that is driving the cell changes all through the body. Periodically dumping plasma and using salt water replacement might actually make older people age backwards.
