I recently read somewhere that someone (possibly the WHO?) when discussing long covid / PVFS using the 3 Rs argument. Rest, rehab, recovery.
Where's convalesence in the 3 Rs? Forget the sound bites. When something doesn't work or we don't know what we're doing then you go back to basics & what you really do know helped. Getting people to convalesce didn't cause panic, stress and undue worry in the 40s & 50s so why should it today?
Maybe rest is their version of convalescence, to fit in with their soundbite?
