Now, you must consider that Peru managed to reduce their death rate to ~0.1% with a lockdown. The situation is terrible but it could have been worse—if they didn’t act.
So: your analysis is minimizing the cost of a death and failing to take into account the reduction in the number of deaths thanks to the lockdown.
Note that in the UK for example the average age of COVID deaths is around 80 with many of those from care homes where their life expectancy is particularly low. This statistic makes the figure of ~10 years of life expectancy lost fairly plausible.
Where did this number come from?
The life expectancy of a 65 years old man is 19 years.
