    Tarkenton utilizes ethos to establish his credibility as the author of such an article due to his NFL career and being an inductee into the Hall of Fame. He emphasizes the time spent as an NFL quarterback and the changes he witnesses throughout his football career due to performance-enhancing drugs. He goes on to question that every sport has encountered problems due to drugs while football being one of the most physically demanding has not arisen any question as to if performance-enhancing drugs are tainting the game. Tarkenton states that at the beginning of his career the “biggest lineman were only around 260 pounds”, now today it is “unusual for a team to have fewer than 10 300-pounders”. Have genetics changed so quickly in the last couple of decades that allow for this, or is there another factor at hand. Through Tarkenton’s credibility it allows the reader to view this problematic issue that has not gained the attention is so desperately needs.…

    Nicotine Research Paper

    An Australian Health Survey conducted in 2011-2012 concluded that 3.1 million Australians are current smokers. (Australian Bureau of Statistics, 2013). This means that 14% of Australia’s population are current smokers compared to more than 40% in the 1980’s – a dramatic decrease with the smoking rate continuing to decline each year. Now there are many factors that can be considered for this drop such as the rise in prices or maybe less accessibility but another big factor is that it’s no longer seen in the same way socially like it was back in the 1980’s. With more and more anti-smoking products being created it decreases the amount of smokers and I’m…
