I am sensing that the metric that determines a "worst year to be alive" is based on life expectancy or rather the lack thereof. Here is a quick factoid -
Life expectancy in the U.S. for the year 1860: 39.4 years
Life expectancy in the U.S. for the year 2020: 78.9 years
Conclusion: Life expectancy has doubled
I am of the belief that life is the greatest of all miracles. Even a life of only 39.4 years can be a wonderful experience. External factors do no change your happiness. Your attitude does. Jehovah's Witnesses have a bad attitude towards life. They are ungrateful for the wonderful experience of life in the here and now because they selfishly desire something more. Life is only precious to them if it is eternal and free from pain.
