With the recent discovery of amateurism, this list should provide proper diagnosis and remediation of disease and illness caused by descending frozen mountains on sticks.
Bummest- a person who avoids work and sponges on others in order to go skiing, often giving up everything in pursuit of shredding everyday, realities of life are temporarily abandoned for short and even long term periods of time. Usually found sleeping in cars or shanties, but always in front of you on powder days.
Professionalism- Some skiers are rewarded so greatly for their talents they become professional. These talents are employed by large companies for the duration of their professionalism as brand representatives. When a person enters the world of ski professionalism, they are instantly absorbed by schedules and demands of said company, leaving skiing last on the schedule. These skiers can be found at the bar telling girls how pro they are.
Amateurism- Those lacking the skills or necessities to enter the world of ski professionalism are borderline bummest, except that they can survive in mountain towns, and ski like a professional. These guys are out skiing everyday, for at least one run.
Shreddaholics- These skiers thrive on the fringe benefits of living in resort towns. Bottom feeding off the riches of resort go-ers (gapers), these skiers lock down personal sponsors and shred next level all day everyday. These guys are known for being on the first chair, shredding most pros under the table, partying till last call, and leaving with the hottest girl in town.
Hateritis- This disease is prone to affect all skiers. Whether the snow condition is whiter on the other side, or a professional skier wins without a grab, every skier hates. Most pros hate on amateurs for skiing all day, whereas amateurs hate for not getting paid. Hateritis can be heard in every terrain park, ski town bar, and the world wide web.
Sidelinest- a person who talks about the ski world and others skiing abilities without possessing any ability of their own. These people are usually involved with large companies or media that enable their sidelining. These guys can be found on the deck of a kicker ranting about someones lack of style.
Brokenness- All skiers are risking life and limb while performing, and from time to time their are injuries. Often severe and requiring surgeries, these dark times can be filled with hateritis, sidelinism, and withdrawl.
Addiciton- At some point everyone must put their sticks up, usually just for the summer season. Some suffer every year as they feel they will never ski again, but as the snow falls every year, most skiers ascend the slippery slopes annually. Some skiers claim to give it up, only to realize the strength of their addiction. Withdrawls can be so severe, some flock to summer ski locations unknowingly entering the world of bumming.
Surprisingly, the only known cure to any of these illnesses is skiing.
