I get the same reaction as you - I'm calm, still, patient. Much more "present" with my wife and far less likely to argue. If I need to plan, or organize something, the initial feeling of "oof" is no longer there. I just do the task.

I have however noticed that my heart rate (normally in the low 50s) hovers in the low 60s. I assume (but have not checked) that my blood pressure is also increasing. Both of these things are concerning.
