The Dem Debate

I'm looking forward to Thursday's debate by the ten Democratic candidates.  Could be a game changer as everyone will be looking to peel off some of Biden's support.  But, three hours?  That is going to take a real marathon effort.  I usually get some help from the team at fivethirtyeight.com with their running commentary on the debaters' performances.  I wish I had that kind of mental agility.  I'm wondering what other strategies people have for sticking it out to the end?
