From what I heard, he got a slow form of scalier radiation poisoning that was time accrued. His career if this is true, is over.
Titor might have been a double effigy creation, which was also replicated in another timeline.
So the problem with the as they say Titor-moble", is that where the twin Kerr's function at an uncertaining level, as a pry-oblate within the flow of time, there was no all scatter radiation protection, within this time slip manifold. So if he became real, then he was getting full juice radiation, as there was no repelling field to protection him. The end result would have been chronic age induction by non-protection from all source radiation.
The same phenomenon that attacked said time travel Al Belick from the Philadelphia Experiment in a US Navy DE class boat, time jumping via Tesla / Einstein mechanics means.
