//complete non sequitur - from down under
The great Barrington Bullshot is a fantasy that no one will get infected over 60 if those under 60 take no precautions//
Really? Where does it say that, then? Here's the full text in case you're interested:

And where does "down under" come into the frame? As I understand it the declaration gets its name from Great Barrington, Massachusetts, where it was signed. The three principle signatories are from Harvard, Stanford and Oxford Universities. Of the other 35 listed on the declaration just two are from New Zealand, the rest from nowhere in the Antipodes.
Having read it, it proposes "focussed protection" based on the risk to individuals rather than the blanket, economy-crippling lockdown approach currently being adopted. It says nothing about what might happen to over 60s or under 60s. You should give it a read. Even I've managed it, as thick as I am.
