Remains the same relative to what/whom? Your point isn’t badly explained. It’s wrong. 

I have no problem in believing that.

But in the twin analog, when twin A reaches the age of twin B, they would have the same number of heart beats, doesn't that mean the tick frequency is the same, but that the ticks of twin B were stretched when compaired to twin A?

Edit, or possibly the other way round...

In which frame of reference?

The twins are the same age at the start of the scenario. One is younger at the conclusion of the experiment. They never “reach” the age of the other.

That seems like a technicality.

All of physics is a technicality. If you’re going to use a scenario, you need to represent it properly, so that everyone is discussing the same thing.

I believe Dim is referring to proper time, tau, ( not co-ordinate time ) which ticks by at exactly one second per second, in everyone's own frame.
If so, he is correct.

The problem with that is, I only speak your language at a remedial level, therefore my imagination is impossible to describe.

I didn't know I was, but that was what I had in mind.
