Have you ever had a life wake-up call?

[Rain Man]

The Rashee Rice thread makes me wonder how often people might have a "wake-up call" to change a behavior. And then I wonder if it's ever permanent.

So...in thinking about things that you might have done that were risky in a bad way, did you ever have a wake-up call that made you permanently change a behavior? If so, what happened and what behavior did it change? And was it a permanent change?

Similarly, have you ever had a temporary wake-up call on something, but then slipped back into the bad habit?

This can be any bad behavior. Maybe it's drugs or alcohol or eatting fatty foods or not wearing a seat belt or engaging in unsafe sex with third-world bargirls or robbing convenience stores or kidnapping hitchhikers or hitchhiking or starting fires by spitting gasoline out of your mouth or doing tightrope walks over deep canyons. Use your imagination.
