On lockdown exit strategy
If a 'calibrated' lifting of the lockdown means sequential opening of different parts of the country, then industrial recovery will be painfully slow. In manufacturing, if even one feeder factory is still locked down, then the final product assembly will be stalled. Research suggests a 49 day lockdown is optimal. If true, then post that duration, I believe the lifting of the lockout should be comprehensive. Containment by exception based on widespread tracking & testing, isolation only of hotspots & vulnerable segments of the population.
