Get hit by a bus or catch the plague

When planning for some less than desirable circumstances, I used to talk about 'getting hit by a bus' as an example of unplanned possible events happening that may need to be considered.
However, as a result of lots of cycling recently, the possibility of being hit by a bus seems a lot more possible. As such I've started using 'catching the plague' as a less likely possibility.

The same thing, just less close to home.
