I don't have a problem with sharing my reasons:
I've been helping take care of people since I was 16. I started as a junior volunteer on the fire department in my hometown, worked my way up from first responder to EMT to Intermediate EMT. I went in the military and became a respiratory therapist and echocardiographer. I've seen a lot of people survive because of the skills of my coworkers and the skills I myself possess.
But to everything there is a dark side, and medicine is not exempt from this. For every person we save, there are some we can't. I'm 24 years old, and off the top of my head I would guess I have seen somewhere in the neighborhood of 800 people die. That's about 4 times the population of my hometown to put in sharp perspective. There are times where I feel as though I am 10 years older than I am in a chronological sense. The long hours and stress have taken their toll on my family and me, I've ruined a good number of relationships because of the idiosyncracies one develops as a result of this work.
I've seen people die in nearly every way imaginable: I've heard the screams of a man burning alive in a car because we couldn't get him out quick enough; I've watched countless people die from drowning in their own fluids because of failing hearts and kidneys, I've watched cancer patients cry blood because they don't have enough platelets to stop the bleeding. I've seen them die in fields and on highways, in ICU's and in mansions and in tar paper shacks. I've seen children face death with great dignity and I've seen grown men cry like babies. Lives ended in the middle of the night or on the brightest of afternoons. Friends, colleagues, and family.....there was nothing we could do to save them. In ones and twos, sometimes more, but not as often, they left this world. I worked the wreck that killed my three best friends. If I hadn't stayed at work to cover for another friend of mine who was running late, I would be dead too because I was supposed to be in the truck with my friends who died. EMS saved my life you might say, but then again the stress damn near killed me.
Emergency medicine, for all the reasons above and many more, takes a toll on people, it's been said the average career of an EMT is about 4 years. I've made it 8. I still do EMS as an avocation, but I've seen too many people die to want to do it as a career ever again. I thought about becoming a physician, but I realized that all I would be doing is limiting the suffering I see into a permanently indoor setting. The fire I once felt for medicine was gone, extinguished like so many of the lives I had seen end before me, despite my best efforts. I began to think of a career in academia, away from the blood, the vomit, and the sundry other bodily fluids I had become so familiar with.
Then I went into to have my teeth worked on by one of the local dentists. I was talking to him and he asked if I was still planning on becoming a doctor (I had treated his child as a respiratory therapist and he knew of my prior ambitions). I told him, no I was not. He seemed disappointed and he asked why. I gave him the same reasons you have just read over, to which he stated, "Have you ever thought about dentistry? You seem to be very talented at taking care of people". He went on to say that he'd been a dentist about 10 years and had never seen anyone die. The hours were stable, the pay is decent, the work is steady and the schooling is challenging, as is the practice of dentistry.
The more I looked into it, the more I became convinced I should become a dentist. The hours would give me the time to pursue hobbies and spend time with my kid (I'll become a dad for the first time in September of this year) and my soon-to-be wife who I adore. But most of all, I think it's a good fit because I get to take care of people and none of them will die on me (hopefully), and I won't be required to stand idly by and watch people suffer. Treating patients and helping them lead better lives is something I enjoy doing more than anything else on this planet. If all the death, destruction and torment I have played witness to have taught me anything that it is this: nothing can put an end to my drive to help people.
I grew up without the benefit of proper dental care- my parents didn't see the value in preventing problems, only trying to fix them and only then when things got really bad. I'm still trying to get all the problems fixed that I have. If I can become a dentist, my goal is that no kid will have to go through what I went through as a child. I run into burning buildings now for no pay, so what could stop me from doing pro bono dental care? Those who can pay, will. Those who can't, well they can be taken care of by those who can.
OK....it's 2 am and I'm rambling.....I'll end this now before it gets too confusing.....
