Was he wearing a mask? Did they screen him before he boarded the plane?
It’s best to have no opinion on containment measures taken until you understand the numbers.
Extrapolating to March, there will be 25% more deaths of 65+ people in the March-March timeframe this year than in normal years. That is happening with all measures taken.
Society has to decide if it will tolerate more deaths in that age range by shutting off all containment measures like lockdown and mask. Or if it cannot tolerate that 25% excess number and must have even more restrictions.
The measures question is separate from the numbers. Understand the 25% number first. Then make your call.
And BTW, 25% increase in 65+ deaths will likely take society’s overall life expectancy down a year or two. 77ish, not 79ish.
