Howling:Is the Thirteenth Doctor's Limit a Psychological Problem or a Physiological One?

This is the spin-off thread for discussing whether the Thirteenth Doctor's limit is a psychological one or a physiological one, from Forum:The Thirteenth Doctor's Death, Tangerineduel and Icecreamdif has raised useful pieces of information concerning this problem. Tangerineduel said,

"The Doctor's death features in Alien Bodies, it's implied in The Five Doctors the Time Lords can give a whole new life cycle to another Time Lord. In one of the New Adventures it's stated the 13 regeneration limit is a psychological one rather than a physical limit. --Tangerineduel 15:58, August 3, 2010 (UTC)2

and Icecreamdif said,

"It definetly wan't a lie that he told his companions. The entire plot of both the Deadly Assassin and the TV Movie was that the Master was out of regenerations, and needed to use the eye of harmony to get a new body and a new regenerative cycle. It would be stupid if they decided to write a way around the regeneration limit, because it would get to be a ridiculous number of doctors, and the Doctor would be more like Captain Jack if it turned out that he was immortal. Matt Smith, and his two successors should just stay on for a while(unlike Christopher Eccleston), and then the show should end when the thirteenth doctor is ready to leave.Icecreamdif 18:50, August 3, 2010 (UTC)"

Are there any more support toward either side of the argument? --222.166.181.242 19:25, August 3, 2010 (UTC)
