Listening to the CVR recordings from flights that did not make it home.
In college, I took a CRM (Crew Resource Management) class and we watched quite a number or analysis of crash, all of them had the CVR tapes included.
Company training also has a few videos of course, and there are also the ones that they show on TV sometimes for documentaries.
It's to make sure we are aware of exactly how things can add up. So we can listen to the guys having their every day conversations, not knowing that they won't have them again. Trying to save an aircraft all the way to the end or having a few moments to realize that there's nothing left you can do. And then there are the ones that never saw it coming.

As much as I sometimes don't neccessarily enjoy it, I try to keep up with various accidents and what caused it. It's always better to learn from the mistakes of others than to repeat them yourself... especially when you might not get a second chance.
Safe flying everyone.
