      • Izzy

        U shut ur face stupid person. If u have nothing good to say say nothing at all. I’m praying for your soul to become better some day

      • you are very rude just because you cant make it as a doctor doesn’t mean nobody else can’t maybe if you did what you were suppose to do while you were in school you could’ve had a chance to, don’t doubt anyone.

      • emmasaid


      • Ayham

        Dear Timbo,
        If you have nothing positive to say, then keep it to yourself. More importantly, you have no need to doubt others who you do not even know. A wise man once said “don’t tell me what I can’t do!” and I’m sure saweta is thinking the same thing,
        Best of luck to you saweta!

      • Nicole

        excuse me but that is very rude you just called me a bad word and i am 10 so don’t go smashing peoples dreams

      • sharkisha landry

I wasted my time and now I have no time to do anything and I might fail my GCSE so don’t do the same mistake that I did please and good luck and never give up achieve your dreams

  3. Cristy

    That is very true bt God gives us the power to understand the human body and help us help others but without him its hard out there

  4. Ikarus

    I agree with cristy…….and also believe that Drs.are gods little helpers.

  5. Dwefvfrevrwgrg

    • I’m sorry!!! But I agree nd disagree with you stupid Rupwa!! CURSE YOU

      • emmasaid


  6. timbo

    you all are a bunch of douche bags with dumb comments go take a shit somewhere idiots. a bunch of foreign idiots who cant write english grammer correctly. and youre all dumb midwest back wood having sex with animals freaks go kill yourself.

    • thepinkprospector

      What kind of irrelevant comment is that? First you curse, then you start stating racist things, and then you call them freaks?! I may be late responding to this, but you seriously need to check yourself before posting stuff like that on a website. If you didn’t like what you saw, then go to another website!

    • Izzy

      Shut the **** up. Apparently u have nothing better to do then to come comment here, so what’s it to u

    • princess


      • Johnejiboy

        Every body study hard so dat u can make it in life. Remember “no cross no crown”.

    • Izzy

      Look who’s talking

    • someone

      Your not at all a nice person , you are saying hurtful things to people you dont even know. But im sure if your were hurt or sick you would rely on a doctor who went through a lot of training to become what they are today………Just stop and think on how hard they worked

    • Shaheera Abbasi

      You are an idiotic psycho hypocrite!You can’t tell other people that they have horrible English grammar when you don’t even have APPROPRIATE English grammar. Didn’t anyone ever teach you about uppercase letters and punctuation? You better not say you are a little kid because no little kid knows half the words you are using.

      I also want you to know that foreign people are very smart, a lot are smarter than the average white people because many citizens of foreign places have been taught in a strict way. I am not saying that white people are dumb I am just saying a lot of foreign people are smarter than the average white person.

      To all the other people reading this comment I know at least a quarter of you either want to quote Thumper and say “If you can’t say something nice, don’t say nothin’ at all” or quote Jacqui Rivait and say “If you don’t have anything nice to say, don’t say anything at all.” I want you to know I am only writing this comment to defend all the other people this person is criticising.

      • Nicole

        You are a great person for standing up for the people that have read this site. I use proper English and I am 10 so to the people that are going “and u r so wright” that is not proper. I am very sorry but it annoys me that you don’t use proper English grammar. I bet most people on this sight are adults so don’t use improper grammar. You have time to type the full thing I bet you.

    • miyah

      what is wrong with u. man people now a days, their brains just don’t work right (aka timbo)

    • Tyrand

      Get a life dum dum who is very very miseries

    • Nicole

      What is wrong with you that one of the most rude comments I have ever heard. Some people on this website want to become a doctor when they grow like me, I am 10 and you called me a bad word. That is mean. I am already studying to become a doctor. And look at you your on this website so doesn’t that mean you called yourself some bad stuff.

  7. timbo is an ass

    your a disturbed person timbo you stupid fuck

  8. Julie

    How exactly did you get from an article on medical careers to awful comments like the ones above? Seriously, if you can’t say something nice and relevant you shouldn’t be posting. The career list was great, I thought is was really helpful.

  9. Marvin

  21. princess

    help me

  22. Izzy

    Now to change the subject from the notorious timbo back to MEDICAL STUFF!!! This page REALLY helped me. I’ve recommended it to a few people already and they loved it too. When I grow up, me and a couple other people already made up our minds and swore on our lives that we are going to start a children’s hospital when we grow up. Its going to be called Hospital for Angels. It’s going to cost money but with the money we make we are going to send over foreign third world country children to be cared for and sent back. This dream is one of those things that will never change.

  23. motivated

    i hope it comes true bro god bless you

    • Izzy

      Well there a lot of things to consider, such as are you good under pressure, can u stand seeing a lot of blood, (surgeon,) are you ok with being in charge of someone’s pain or sleep (anesthesiologist,) do u like to know about people’s genes and heredity, (pathologist, paleopathologisy, medical genetist,) do u like to look at bones, find casts interesting, (radiologist, orthopedic surgeon/specialist,) do u like children, have great patience, (pediatrician, general practitioner (family doctor,) do u get along great with others, especially children, understand others greatly, not afraid to bring up the worst and best case scenarios for anything thrown at you, (physiatrist, physiologist,) etc.

  28. I really want to be a doctor but I don’t know what kind of doctor I can do ??

    • Izzy

      (I copied this from my above reply) Well there a lot of things to consider, such as are you good under pressure, can u stand seeing a lot of blood, (surgeon,) are you ok with being in charge of someone’s pain or sleep (anesthesiologist,) do u like to know about people’s genes and heredity, (pathologist, paleopathologisy, medical genetist,) do u like to look at bones, find casts interesting, (radiologist, orthopedic surgeon/specialist,) do u like children, have great patience, (pediatrician, general practitioner (family doctor,) do u get along great with others, especially children, understand others greatly, not afraid to bring up the worst and best case scenarios for anything thrown at you, (psychiatrist , psychologist,) etc.

  29. srishti

    i just want’s to become a doctor because doctors are very good and they saves our life……

  30. name

    I always wished to become a doctor as well. Although i fell discouraged recently because I learned i am kind of in a predicament trying to learn biology. Is there any chance i may still be a doctor without knowing an successfully learning “Biology.”??

    • Izzy

      U could start a hospital if ur good at engineering

      • name

        Thats the thing, i dont really “know” what Im good at; I just always wanted to be a doctor. Some of my choices include Hematology, Paleopathology, or Neonatology. I just worry that i wont be able to make it into the medical field due to the fact that i am not the best in science.

      • Izzy

        Do u believe in god? Because if u do pray to him for help. Continue studying ur science and if it truly is not ur path god will tell u and help u. Just put ur whole faith into Him and u WILL succeed. My promise.
