Hmm lock away all the 70+ for 4 months. Is that feasible. What about the 60-70 that are also at risk and all those with pre-existing conditions. Who is going to take care of all the 70+ in retirement homes and those that need help daily. Who is going to bring them decontaminated food etc.
They are deeply worried that some older people will simply die at home from neglect, after they are quarantined, so want to start the quarantine as late as possible - some time within the next five to 20 days.
Wacky idea, and looking at Italy it's not just 70+ that need the ICU...
