How common was death in the arena?

[Titus Manlius Verus]

-Bump- Perhaps a reason could be that as Gladiator bouts became less common, the mob consequently expected even bloodier spectacles to make up for the infrequency of games. It would be like today, if football matches were held on a more infrequent basis. wouldn't you want the matches to be more exciting if they were held,say, only once a year? That's just my imput. I normally don't bump old topics, but I found this one to be interesting.
