Looks the same as pediatricians. Even when no drug is needed they'll still give it to you. My dad has an inflammation on his foot, and the doctor gave him patches, only to find out later that those patches could cause stomach problems. o_O It's not a digestable pill, but a patch you put on your foot, and that still has side-effects on other parts of the body??
Sorry if I sounded impudent, but you said before that you been in Australia long enough to know that not a lot of television ads circle around medicine. That sounded like you moved to Australia--but that doesn't matter. I'm not "American blood" either lol. I'm Indian, but born and raised in the US. My mom and her parents lived in England for a while so that's what explains the dual citizenship, if I haven't explained that already. But both my parents are from India.
Same with engineering, to be independent you must have that professional license, or have a Master's/Ph.D. Yeah to get a Ph.D in engineering it's 7 years. For a master's it's typically 2 years after undergraduate studies, but for our uni we could get a BS and MS in five years as an undergraduate. My uni wasn't very popular, except in the city, Philadelphia. It is a private university. But it's getting its recognition in the engineering world.
