I don't agree with that 95%. I would say it's more like 45% which is pretty high too. The thing is most people in EMS are not married to those in it themselves. And those spouses which are not in EMS or even interested in it generally don't understand your job or your attraction to it. Therefore, you can't talk about your work day without feeling like they don't care or it's not worth explaining because they don't understand anyway. Eventually, you grow apart because you have nothing in common anymore. UNLESS, you are extremely dedicated to "family first" and making time for them which is really hard in this business because you are always either at work or at school, con-ed, taking second calls, etc.
Also, it is easy for two people who work side by side and as closely as we do to develop some sort of emotional attachment for each other. Especially when you eat, sleep and work together for 24 hrs. That being said, i think that people should switch partners as often as possible as not to develop this. Most squads will not allow you to have the same partner all the time. Just as many clash as they do clique.
It really all boils down to one thing though:
SELF-CONTROL!!!
Not many people have much of this.
