But a .2% mortality rate from COVID-19 means that if you're in your 20s and catch it, your odds of dying this year will have more than doubled! You think that's not worth worrying about? On a global scale that is millions of potential deaths beyond the prior statistical expectation.
Relative differences can be completely meaningless if the absolute numbers are tiny. The chance of you being hit by a meteorite in your lifetime is 1 out of 700'000 and being bitten by a shark is 1 out of 8'000'000. Does that mean you should worry more 10 times more about being hit by a rock from space?
No, both are such small numbers that you shouldn't worry about either.
