You can talk about til the cows come home, you either get it, or you won't.
Yes, but it's what happens when you DO get it that worries people!
So put that in perspective, on average, 10 people die on the roads every day...
AAAAGH!!! Ban roads! I think this comes back to our cultural take on mortality - it's accepted that doing silly things sometimes leads to death or injury, which is why people still bungee jump, parachute, eat doner kebabs etc. If someone dies whilst climbing a skyscraper without gear, it's a tragedy but people move on because you had it coming.
But, with flu, it isn't a risk that you subjected yourself to. It's all around, the only way to avoid it is to live in a bubble. Which means it just isn't fair.
In more religious countries, people accept this sort of thing as God's will and move on with their lives. Gone to a better place, it was his time, had a good innings etc.
