Yes, I always try my best.
According to:
wikipedia.org/wiki/List_of_countries_by_life_expectancy
who.int/gho/publications/world_health_statistics/2016/Annex_B/en
Singapore's life expectancy is almost exactly the same as Japan's at the top of the world rankings, right?
That depends on how you measure "wealth", and I would agree with you that Japan is wealthier in certain senses.

But Singapore is certainly wealthier in terms of:

Then why is Japan's suicide rate
much higher than Singapore's, as I mentioned earlier?

And why is Japan world-famous/notorious for:
wikipedia.org/wiki/Karōshi
whereas Singapore is not?
To be fair, you would have to compare Singapore with Tokyo, since Singapore is also a city.
And that's why I like Japan, as I said earlier.

But having said that, Japan also has its share of human "scum" or outcasts:

If you have been living in Singapore most of the time for at least the past decade, you should know that is simply
not true.

During the past decade, there have only been three serious haze crises in Singapore, and they were
not even natural disasters, but
preventable man-made disasters:

wikipedia.org/wiki/2015_Southeast_Asian_haze
wikipedia.org/wiki/2016_Southeast_Asian_haze
haha, that is obviously
not true!
Like I've said earlier, Japan also has its fair share of diseases.
Yes, I agree that Singapore has too many foreigners. :(
Since you used the word "figure", I'll literally give you some figures.

During the past twenty years, just these two earthquakes:
wikipedia.org/wiki/1995_Kobe_earthquake
wikipedia.org/wiki/2011_Tōhoku_earthquake_and_tsunami
killed at least
twenty thousand people, injured tens of thousands more, and caused many more to become homeless or missing.
Every year, the Japanese are well-aware that the next big earthquake could happen before the year ends:
wikipedia.org/wiki/List_of_earthquakes_in_Japan
Just earlier this year, the:
wikipedia.org/wiki/2016_Kumamoto_earthquakes
killed about 50 people and injured about 3,000 people in the
capital city of Kumamoto Prefecture.
As for Singapore's
"deadly dengue sars or tb or zika etc.", how many Sinkies have those diseases killed?

If you can, please show me the evidence for as precise a number as possible.
