Note, this is the general trend, but has NOT always happened.
Judging by actor age at the start of their run, Three was older than Two, Six was older than Five, I'd have to check again but Seven looked older than Six, and Nine was older than Eight.
I love the WMG! It fits so well, aside from the ginger-Doctor bit.
