“Look at that machine, he/she is on Steroids!” Critics of Hardworkers

Why is that no matter what an improving athlete does in the offseason, there are always critics? Why do the critics always jump to the conclusion that the critics always jokingly, but yet seriously always quote, “Steroids”?
How many people in this world, at first glance called Ben Johnson, the former Canadian world-class sprinter a, “doper” or steroid user? Johnson first came on to the world scene of track and field in 1982 at the Commonwealth Games in Australia and was last noted in the 1988 Olympics in Korea. In 1982, at the ripe age of 21 years old Johnson ran 10.05 seconds in the 100 meters and six years later ran a unofficial world-record time of 9.79 seconds in the 100 meter dash in Seoul, Korea, before being disqualified due to failing a drug test. Johnson was fast when he came onto the scene, and through hard work and a “few” artificial helpers elevated his performance. But lets stop and think about this for one second, it has been almost 20 years since Johnson’s feat of 9.79 seconds and what is the world-record 100 meter time now, are the current runners on steroids too, since back in 1988, it was humanly impossible to run faster that 9.8 seconds in the 100?
Just this past weekend, Jamaica’s Usain Bolt ran 9.58 seconds in the 100 meter dash at the World Championships in Germany to shatter his own record set one year before at the Beijing Olympics. If Bolt were on steroids, wouldn’t the drug tests show?
I have never understood the thought of hard work being criticized, but in this day and age it is always easier to cut somebody else down, than actually do something yourself. The person who talks a good game is too busy talking, when the competitors trying to get better are in the gym or on the field attempting to get better. The person who is usually talking the talk, trips over their own feet, while they are walking the walk, too bad they can’t choke on their own words, when accusing of, “Steroids”.
Everybody needs to encourage and give accolades to some of the few that choose to put in the hours and sweat to make themselves and their teams better in the offseason.
Why does everybody always consider great accomplishments to be tainted, in some peculiar way, no matter the achievement?
