Dan Tani the astronaut lost his 90 year old mother when
she died after being hit by a train near Chicago.
Dan Tani happened to be onboard ISS at the time
and didn't find out about the tragedy until a video-conference
with his wife and flight-surgeon.
Sadly, he will not return to Earth until at least January
to visit her grave.

He will have a melancoly and depressing Christmas.
I know what it's like.
However, I suspect that he's got a tough spirit...
He'll endure that day.

But there is a future scenario that threatens:
What about an astronaut on his way to Mars who learns that
he lost his wife and children in a car accident, while he is tens of millions of
kilometers from Earth, with minutes of light-speed comlink delay?
And no way to return to Earth for one or two years?
Could that astronaut become suicidal?
Threatening a multi-billion dollar manned Mars mission?

And know people know that astronauts aren't the only people at risk every day:
A stray bullet here.
A car crash there.
A train wreck some place.
An airplane goes down.
A doctor informing you of cancer.
A sharp pain in the chest.
A shark attack off Florida.
An unexpected earthquake in California.
A collapsing bridge.
A snake bite in Arizona or Australia or
a deadly virus from China.
etc.....etc.....etc....

All these are daily risks we encounter.
Add up the risk sum of all potential hazardous and lethal circumstances and we are no less at risk at 'daily living' than those astronauts who board dangerous rockets.
