How long does it take before you outburst?

It really depends on what that something is...if a young child is crying people may not be able to control their first feelings and feel sick or unwell from it....while others may just feel annoyed or angry compared to brain stimulus to some sort of pain one can draw from it or emotional pain.
Some people can be easily overwhelmed but that doesn't always stem from maturity or even intelligence, ranging from trauma, mental to social illnesses...some people cannot help what they will feel naturally first before anything else....but that does not exclude someone from what they do outwardly compared to inward no control of physical/emotional pain.
I was in a war, I did everything I could to keep my people safe, so was under a lot of pressure but I had a great deal of perseverance and calm in me that not everyone has or feels. There are still things that happen in my own house whether it be from cptsd or something that hurts me in a way I cannot understand where I cannot feel anything but jumpy and tend to be overprotective of my home...if anyone were to come I would take action.
I will not tolerate and I mean it in any way, anyone who will not listen to me and someone who hurts others.
