It's not reasonable at all. You're 1 instance of bad luck away from death. But that's hardly a reason to not leave home.
Personally I have still friends I cannot switch to other platforms so I am stuck checking my Facebook messages once a month, but that is the only reason I still have an account, and I have unliked everything else from the service.
You obviously can't remove all risk, but you sure can reduce it.
Can you back that up? I thought this was true too but did a quick check anyway and I found skydiving death rates are 8 in a million but driving death rates are 7.1 per billion kilometers. Driving to the airport is probably more dangerous than your average drive, but it still looks like the car trip is less likely to kill you.
