Performance-Enhancing Drugs Imagine that you’re one of an elite group of students fighting for a spot at the top of your class. You’re fully aware of the implications of an upcoming exam. If you blow it, you lose your rank. However, a good grade virtually assures you of prestige and a comfortable job. So you look for that extra edge – a little something to push your already strained mind further. If there was a pill that would increase your mental sharpness for a short period of time and ensure you a high score, chances are many of you would consider taking it. Amateur and professional athletes are faced with a similar dilemma every day of their competitive lives. In the never-ending search for the extra edge in sports, many athletes have given in to the lure of performance enhancing drugs. PREVIEW STATEMENT Today I will be talking with you about the types of performance enhancing drugs used by athletes, side effects and dangers of these drugs and what the sports industry is doing to combat their use. CONCLUSION In conclusion, no matter how safe you think taking these drugs will be, the risk will always outweigh the edge given to the athlete. The risk to their health and their athletic career isn’t worth a temporary competitive edge. The best bet in life is to just work hard and do your best. 6.

PREVIEW STATEMENT Today I am going to talk to you about the how laughter can boost your mood and why people says it’s the best medicine.
