I understand that perspective but I'm not sure the experience from over a century ago has much relevance to today. Would the Spanish Flu have killed so many today, with such advanced hospitals and healthcare, and no massive troop movements? We see flu pretty regularly and no lockdown is even proposed, as it's obvious the costs would be stagggeringly out of proportion.
